How can i figure cubic feet

As mentioned above, a cube with a volume of one cubic foot has sides that are one foot in each dimension. See the table below for the dimensions in other units of measure. This calculator supports calculating the volume for a cube or rectangle; check out our our volume calculator to find the volume of even more shapes.

Start by locating the formula in the table above. CFT is also known as cubic feet or ft3, a unit measurement of volume, a cubic foot is the space occupied by a cube with 1 foot width, length and height.

Here is how to figure out the cubic feet, if your unit of measurement is not feet, convert the nuit to feet first, then, multiply length, width and height values together, this will give you the volume of the cube. Convert from measurements in inches to cubic feet, when we measure the dimension of a carton with a ruler, the unit is inches, and we need calculate the cubic feet.

If you don't want to convert the unit to feet first, that's ok, below are formulas for other units. So, if you want to calculate the volume of a box-shaped object, the formula for volume looks as follows:. But what do we do if the dimensions are expressed in units other than feet - like yards, inches or even centimeters and meters?

Well, you need to convert them. There are two ways of doing this - either you convert the units before the volume calculation or after:.

After converting the units you'll have all of the dimensions in feet, so a simple multiplication will give us the result in cubic feet.

If you are dealing with a different unit for each dimension we recommend using first method to avoid miscalculations. Or, even better, you can use our cubic feet calculator and forget about tricky unit conversions! Let's have a look at the example. Assume that you have an oven with its dimensions expressed in inches:. So, how do we calculate its volume in cubic feet?

Let's find it using to two methods we outlined in the paragraph above:. The result is, of course, the same. It wasn't so hard to calculate cubic feet from inches, wasn't it? Fear makes things look twice as bad as they are.

Calculating cubic feet of soil is no different than calculating the standard volume! All you need to do is find the volume of soil required:. Let's assume we have a length of 10 yards and a width of 3 yards, so then the area would be equal to:.

If the area you want to cover has a more irregular shape, you can try dividing the area into a couple of rectangles and calculating their areas separately before sum them up.
