What is 28x42x9.5 in cubic feet - Office Equipment & Supplies

You can't convert cubic feet to square feet because cubic feet has an extra dimension, you could fit an unlimited number of square feet into cubic feet.

The formula for Cubic feet is:
length × width × height

The formula for Square feet is:
length × width

How it Works

Stone and Mulch Calculators

As an example, let's use 500 square feet to be mulched at a
3" depth.

1. First, the depth must be converted to feet. To convert inches to feet, simply divide inches by 12, the number of inches in a foot.
   
   So for our example: 3 inches divided by 12 equals a 0.25 foot depth.
2. Now that we have the depth in feet, we can multiply the depth by the area.
   
   So for our example: 0.25 foot depth times 500 square feet equals 125 cubic feet.
3. If you are calculating 0.5, 2, or 3, cubic foot bags, simply divide 125 cubic feet by the size of the bag.
   
   So for our example: if we are using 2 cubic foot bags, we can divide 125 cubic feet by 2 which equals 62.5 bags.
4. If you are calculating cubic yards, we need to convert 125 cubic feet to cubic yards by dividing by 27. One cubic yard is equal to 27 cubic feet, see the diagram below.
   
   
   
   So for our example: 125 cubic feet divided by 27 equals 4.63 cubic yards.

For Your Information

• 1 inch equals 0.08333 feet
• 1.5 inches equals 0.125 feet
• 2 inc

First step - convert everything to feet - 5" is 5/12 of a foot

40 x 4 x 5/12 = 66.6 cubic feet.

Since a cubic yard is 3 feet by 3 feet by 3 feet, there are 27 cubic feet in a cubic yard.

66.6 cubic feet / 27 cubic feet/cubic yard = 2.5 cubic yards.

Good luck.

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.

Multiply 21 inches by 14 inches by 10 inches to get 2940 cubic inches. There are 12 inches in a foot, so there are 12^3=1728 cubic inches in a cubic foot. Divide 2940 cubic inches by 1728 cubic inches per cubic foot to get about 1.7 cubic feet.

Alternatively, first convert all measurements to feet. 21 inches is 1 3/4 feet, 14 inches is 1 1/6 feet, 10 inches is 5/6 feet. Multiply them together to get 245/144 cubic feet, which again is about 1.7 cubic feet.

It's always nice when doing a problem two different ways gives the same answer.

What unit are the numbers in?
40 feet by 45 feet by 5 feet is 9000 cubic feet.
If the numbers are in inches then the volume is about 5.2 cubic feet.
If the numbers are in meters then the volume is about 317,832 cubic feet.
