One may also ask, how do you calculate the thickness of a concrete slab? How to calculate concrete:

1. Determine how thick you want the concrete.
2. Measure the length and width that you'd like to cover.
3. Multiply the length by the width to determine square footage.
4. Convert the thickness from inches to feet.
5. Multiply the thickness in feet by the square footage to determine cubic feet.
