The image above shows the difference between the two measurements. Because these are completely different types of measure, you’ll need some additional data to convert between the two. In order to convert either way, you’ll need the height of the space.

How to Convert Square Feet to Cubic Feet
To convert square feet to cubic feet using the area and height, you’ll need to use a conversion formula.

Square Ft to Cubic Ft Formula
You can use the following formula to convert square feet to cubic feet:

cu ft = sq ft × height

The volume in cubic feet is equal to the area in square feet times the height in feet. 

For example, let’s calculate the cubic footage of a 100 square foot area that is 8 feet high.

volume = 100 sq ft × 8 ft
volume = 800 cu ft
