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.

How much area will be covered with 36.78 cubic feet of mulch please answer in feet and inches


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

I need to replace microwave and don't know what size in cubic feet?


Multiply interior's height x width x depth. Ex: lets say 10 inches x 12 inches x 8 inches = 10 x 12 = 120 x 8 = 960. Divide 960 by 1728 (12 x 12 x 12) =. 56 cubic ft( point 56) just a tad more then half cubic ft.

WHAT IS THE CUBIC FEET OF JVM1339WB-002 GE MICROWAVE SPACE SAVER?


Determining the cubic feet of any given appliance, Microwave, Oven, Freezer or Refrigerator is quite simple.
Follow these steps.

Open the door of your microwave and measure the length, width and height in inches of the interior cavity.
Multiply the length by the width by the height using a calculator to get the total in cubic inches.
Divide the cubic inches by 1,728, which is the volume of a cubic foot. The resulting number will be your microwave's measurement in cubic feet. You can also use an online conversion calculator to simplify matters

Hope that helps

I measured a freezer in inches which Are 20 30 20 Please calculate in cibic feet


20 inches times 30 inches times 20 inches is 12,000 cubic inches. There are 12 inches in a foot, so one foot is 12^3 or 1728 cubic feet. 12,000 cubic inches divided by 1728 cubic inches per cubic foot is about 6.9 cubic feet.

We have the GE JVM130H 001 microwave. I am trying to figure out what is the cubic feet capacity of this microwave. Can anyone tell me?


Hi, W/D here.

Here's an easy way to calculate your cubic feet: measure and multiply (in inches) the width X depth X height, then divide by 1728. This will give you cubic feet.
For example, if a microwave measured 18" wide X 18" deep X 12" high, it would be 3888 cubic inches; divided by 1728 (cubic inches in one cubic foot) = 2.25 cu.ft.

Size of older GW Microwave


If you want to calculate the volume of an object and have the answer in cubic feet.

Volume=Length X Width X Height
With the dimensions you give
Volume=12.5in X 37in X 20in
Volume=9250 cubic inches

To convert 9250 cubic inches into cubic feet you need to understand that there are 1728 cubic inches in 1 cubic foot.
L X W X H = 12"X12"X12"=1728 cu in

You then multiply 9250cu in and (1/1728cu ft) Really you are dividing 9250 by 1728.
your answer is 5.35 cubic feet.

12 inches in 1 foot
144 square inches in 1 square foot
1728 cubic inches in 1 cubic foot

to convert you put the unit you want to keep on top of the dividend.
to conver to to feet ( randomly selecting 100 inches)
Example converting 100 inches to feet

100inches X ____1ft____ = (100/12) = 8.3 feet
12inches

or cubic inches to cubic feet
4000 cubic inches to cubic feet

4000cu in X ____1cu ft____ = ( 2.33 cu ft)
1728 cu in

if you notice that the units on top and bottom of the dividend cancel each other out leaving the numerator (top number) as your unit.
it also works in reverse

2.33 cu ft X ___1728 cu in____ = (4000 cu in)
1cu ft
