To use the Concrete Volume Calculator, which measurements must you enter?

• A. Width, Length, and Thickness
• B. Height, Width, and Thickness
• C. Length, Width, and Density
• D. Height, Length, and Density

Answer: (A)

To calculate concrete volume, you use the three linear dimensions that define a rectangular pour. The volume equals length times width times thickness, so you must enter width, length, and thickness. Thickness is the vertical dimension of the slab, while length and width define the base area. Density isn’t needed for the volume itself (it would be used later if you want weight), and height is simply another term for a vertical dimension but the calculator expects thickness. Make sure your units are consistent (all in feet or all in meters) to get the correct volume.
