A grease interceptor/separator that is 5-feet long, 3-feet wide, and 36-inches deep will require the removal of approximately how many cubic feet of soil and concrete flooring debris?

To determine the volume of soil and concrete flooring debris that requires removal for a grease interceptor/separator, it's essential to first calculate the total volume based on the dimensions given: length, width, and depth of the unit.

The grease interceptor measures 5 feet long, 3 feet wide, and 36 inches deep. To calculate the volume in cubic feet, we need to convert the depth from inches to feet. As there are 12 inches in a foot, 36 inches converts to 3 feet (36 ÷ 12 = 3).

Now, we can calculate the volume using the formula for the volume of a rectangular prism:

Volume = Length × Width × Depth

Volume = 5 feet × 3 feet × 3 feet

Calculating this gives:

Volume = 5 × 3 × 3 = 45 cubic feet

Since the question asks for an approximate range of the volume, 45 cubic feet falls within the range of 43 to 47 cubic feet, making this the correct answer. This also helps reinforce the concept that understanding how to calculate the volume of three-dimensional objects is critical in plumbing and construction work. By knowing how to visualize and compute volume, a plumber can accurately assess the material requirements for
