Find the volume of irregular elliptical pyramid with Length is 140 feet Diameter 1 (width) is 85 feet Diameter 2 (thickness) is 26 feet

You can convert pipe size to gallons per minute of flow by calculating the cross-sectional area of the pipe and making some reasonable assumptions about pipe volume and the rate of flow. Pipe sizing is measured by the internal diameter of the pipe, not the overall outside diameter. Once determined, the overall volume can be calculated. Pipe flow is described in gallons per minute. Shorter lengths of pipe will have a greater flow than a longer length of the same diameter. This is caused by internal resistance of the pipe itself. By the same reasoning a larger diameter pipe will have a greater flow or GPM than a smaller pipe at the same pressure or flow rate. Pressure is described as pounds per square inch. The square-inch measurement is determined by the area of the pipe. The pounds are the amount of force that is placed on the liquid to push it through the enclosed space.With that background, you can estimate the flow based on the pipe size.
Find the cross-section area of the pipe. Area is equal to pi times the radius squared or a = 3.14 x r2. A two-inch diameter pipe would have a cross-section area of 3.14 x 12 or 3.14 square inches.
Understand that water has a certain pressure associated with the height of that water. One pound of water pressure, or 1 PSI, is equal to 2.31 feet of elevation in height. In other words, a 1-inch column or pipe of water that is 2.31 feet high will have a pressure of 1 PSI. The overall height -- not volume -- of the pipe corresponds to the pressure. A 6-inch diameter pipe that is 2.31 feet high will only have 1 PSI.
Find the volume of the 2-inch diameter pipe in Step 1 that has a length of 10 feet. Ten feet is equal to 120 inches. Multiply 3.14 square inches, the cross sectional area, times the length. The volume of the pipe is equal to 376.8 cubic inches of volume.
Convert cubic inches into cubic feet. One cubic foot equals 1,728 cubic inches. Divide 376.8 cubic inches by 1,728 cubic inches per cubic foot and the answer is .218 cubic feet. This means that the 2-inch diameter pipe that is 10 feet long has an internal volume of .218 cubic feet.
Calculate the amount of water that can be contained in the section of pipe at any given time. One cubic foot of water is equal to 7.48 gallons. Multiply 7.48 gallons by .218 cubic feet and the amount of water in the pipe is equal to 1.63 gallons.
Find the GPM if the flow of water is one foot per second. Multiply the one-foot per second flow by 60 seconds per minute and the flow is now 60 feet per minute. In other words the water will flow through the 10-foot pipe six full volumes for every minute. Since the piping contains 1.63 gallons per 10 feet of pipe, multiply 1.63 by six and the final GPM is equal to 9.78 GPM of water flow from the 2-inch diameter pipe.

your measurements are in different units, say feet and inches, you can first convert those values to feet, then multiply them together to get the square footage of the area. If you are measuring a square or rectangle area, multiply length times width; Length x Width = Area.

linear feet is a length measurement as to how long it is --example : a piece of timber 20 feet long is 20 linear feet
the measurements you have provided will give a cubic feet measurements which is a volume measurement. so convert all the dimensions to feet , multiply all together and that will be your volume

Not enough information to answer. For AREA, you multiply length times width and get square feet. For VOLUME you multiply length times width times height and get cubic feet. You need a third value to calculate cubic feet.

Calculating the cubic feet of a space requires multiplying the area of the bottom times the average height. You get the bottom area by multiplying the length times the width. Remember, to get cubic feet, you need all your measurements in feet to start with.

Here is your formula:

VOLUME (in cubic feet) = Length (in feet) X Width (in feet) X Height (in feet)

If it's a rectangular room you're working with, it is all straightforward. If there are irregular walls, it may be necessary to divide up the room into rectangular sections and then add together their individual volumes. If the ceiling is sloped, you need to use the height that has the same ceiling area above it as below it. Good luck! Truly.

Assuming the new hexagon will be the same 12.5 width, the length would be the current length MINUS 8.8 feet (approx 8' 9.6" less)

Linear feet are a measure of length (no different from feet); square feet measure area. You cannot simply convert between measures of different kinds of quantities;the connection between them will be specific to a particular problem.A practical example in which this question can arise is in buying countertops for a kitchen. Some materials are sold by the square foot; others (basically those that are extruded, so they come in standard widths) are sold by the linear foot. In order to compare the two, you need to compute the area and wall length for the countertop you want.You can't convert between the two. All you have to do is to make the appropriate measurements so you can calculate the price of each item.The terms used in the lumber industry are a bit confusing.There are two terms that I think you might be mixing up.A LINEAR FOOT is simply the length of a board. If you want to know the area or volume of the board,you need additional information. For instance, 6 linear feet of 1-by-12 has an area of 6 square feet (12 inches = 1 foot, times 6 feet), and it's 1 inch thick, so the volume is 1/2 cubic foot (6 square feet times 1/12 foot). But 6 linear feet of a 1-by-6 board would have half the area and half the volume.A BOARD FOOT is equivalent to one square foot of a 1-inch-thick board. In other words, it is a square-foot-inch (ft^2-in), or 1/12 cubic foot.Linear feet are used for the pricing of a single size such as two-by-fours. Board feet are used for larger lumber that you are more likely to want to compare directly with different size boards .To sum up, neither a linear foot nor a board foot can be converted directly to square feet. A linear foot is a linear (length) measure, and a board foot is a volume measure. You need to know your particular board to do anything more, such as find the area.an example with an" L" shaped countertop will betwo rectangles are 24 by 80 inches and 24 by 36 inches. Thus the area is: 24 * 80 + 24 * 36 = 24 * (80 + 36) = 24 * 116= 2784 sq. in.To get it in square feet, divide by 144:
2784 / 144 = 19.33 sq. ft.The linear measure of this countertop would be 60 + 80 = 140 inches = 140/12 feet = 11.67 feet

A pipe can be seen as two cylinders, one of "air" sitting inside the other, in this case lead.
To get the volume of a pipe you thus subtract the volume of the "air" cylinder from that of the lead cylinder.
Volume of a cylinder = area of circular cross section (or pi times square of the radius) times the height (or length) => ? * r2 * h
Volume of a pipe = Volume of cylinder 1 (outer diameter) - volume of cylinder 2 (inner diameter).

In this case; Volume of outer cylinder => inner diameter 1/2" (0.5") + pipe thickness 1/4" (0.25") = 3/4" (0.75") divided by 2 to get radius = 0.375".
3.14 (?) * 0.375 * 0.375 * 120(10 feet) = 53.01438 in3

Volume of inner cylinder => inner diameter 1/2" (0.5") divided by 2 to get radius = 0.25".
3.14 (?) * 0.25 * 0.25 * 120(10 feet) = 23.56194 in3

Volume of lead in this pipe = 53.01438 - 23.56194 = 29.45244 in3

Hope this helps ;)

1 cubit [Roman] is 17.4803149606 inches

If you are referring to cubic feet to inches then you need cannot when cubic feet is a volume measurement and inches is a length measurement.

3.14 x Diameter x Diameter / 4 x length= Volume in Cubic inches Diameter and Length are in inches.

Multiply the above volume by 0.004 to get gallons.
