# How to Find the Volume to the Nearest Cubic Foot

A cubic foot is a measurement that encompasses a shape that is 1 foot wide, 1 foot tall and 1 foot long. To find a cubic feet volume measurement, you multiply the height, length and width of an object that's in the form of a rectangular prism. If you want to find the volume to the nearest cubic foot, you'll have to perform a bit of rounding to arrive at a whole number once you find your volume measurement

## Step 1

Find the volume of your object in cubic feet. Stretch a tape measure across your object and find the length, width and height in feet. Multiply all these numbers together to find the volume. For example, measurements of 3 feet by 2.2 feet by 6 feet produce a volume of 39.6 cubic feet.

## Step 2

Round your volume measurement up to the nearest whole number if the number to the right of the decimal point is 5 or higher. For example, in 39.6 cubic feet, the decimal number of 6 causes the entire number to be rounded to 40 cubic feet.

## Step 3

Round your volume measurement down to the nearest whole number if the number to the right of the decimal point is 4 or lower. For example, if your volume measurement was 39.4 cubic feet, the 4 would require you to round the whole number down to 39 cubic feet.
