What is the correct volume formula for a rectangular wet well?

• A. V = L x W x C
• B. V = W x A x P
• C. V = W x L x H
• D. V = W x H x D

Answer: (C)

The volume of a rectangular wet well is found by treating it as a rectangular prism and multiplying its three dimensions: length, width, and height. The base area is length times width, and multiplying by the vertical dimension (height) gives V = L × W × H. Because multiplication is commutative, you can write it as V = W × L × H as well, which is why this form is correct. If the dimensions are in feet, the result is in cubic feet; in meters, in cubic meters. Other forms that use nonstandard symbols for the height or introduce extra factors don’t represent the three spatial dimensions of the well and won’t give the correct volume.
