I want to buy a GE electric double oven model #JRP28BJBB 24 inch that has 2.7 cubic feet. what are the inside dimensions in inches that make up the 2.7 cubic feet?

with x height x depth = cubes

remember to measure the inside of the oven. not the outside

23 x 29 x height / 1728 = cubic feet

you divide it by 1728 because that is how many cubic inches there is in one cubic foot (12x12x12)

Just measure the inside dimensions of the unit in inches. Get the length, width and height then use this formula: (L x W x H)/12 = Cubic Feet

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

72 x 29 x 24 = 50,112 cubic inches / 1728* = 29 cubic feet. There are 7.48 gallons per cubic foot, so the tank is actually 216.92 gallons, assuming the dimensions given are inside measurements. I hope you have a strong stand and floor because the water alone weighs 1735.36 pounds (8 pounds per gallon).

*12 x 12 x 12 = 1728 (cubic inches to cubic feet conversion)

Easiest solution is to measure the inside dimensions in inches, tall, width and depth. Then multiply the three dimensions t x w x d = cubic inches. To get cubic feet then divide the above answer by 1728 and the result is cubic feet..

For instance if the fridge is 60 inches tall x 24 inches wide x 18 inches deep; the answer is 60 x 24 x 18 = 25,929 cubic inches... 25,920 divided by 1728 = 15 cubic feet.

The quickest way would be to measure the Volume inside of the unit. Height, Width and Depth. Example: Height 60 inches, width 24 inches, depth 24 inches then divide by 1728(Cubic inches in a Cubic foot 12x12x12). 24x24x60 = 34560 / 1728 = 20 cubic feet

Measure the width, depth, and height in inches of the interior cavity.

Multiply the length by the width by the height to get the total in cubic inches.

Divide the cubic inches by 1,728.

The resulting number will be your microwave's capacity in cubic feet.

Measure Exterior Height & Width and Depth for Dimension.
Interior Space = Then, Measure all open accessible area inside the fridge and add the two together, following the formula of H+W+L Freezer and H+W+L Refrigerator,add together and BAM ya got cubic inches.= Square inches, then divide by 1,728 (the number of cubic inches in a foot (3) Cubed.
Example 1: 60 inches tall, 42 inches wide, 30 inches deep = 75600/1728 = 43.75 Cubic Foot AREA
Example 2: fREEZER dIMS = 24 DEEP x 18 HIGH x 36 WIDE =15552/1728 is 9 CuFt. Refridgerator 36 wide, 36 high 28 deep = 36,288/1728 = 21 CuFt. + 9 CuFt. = 30 Cubic Foot Capacity.

get a measureing tape measure inside dimensions multiply them together eg: a freezer with an inside dimension of 2' X 2' X 3' would equal 12 cubic feet if want an exact value measure in inches 24" X 24" X 36" = 20736 and divide by 1728 will give you cubic feet cool eh.. where did I get the 1728? (12 X 12 X 12) =1728 converts cubic inches to cubic feet Good Luck let me know when you pour that cement pad for under your shed I tell you how many yards to order

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
