A grease interceptor that is 2-feet long, 2'-6'' wide, and 3-¾-feet high will approximately contain how many gallons of water?

To determine the volume of the grease interceptor in gallons, you first calculate its volume in cubic feet and then convert that to gallons.

The dimensions given are:

• Length: 2 feet

• Width: 2 feet 6 inches (which converts to 2.5 feet)

• Height: 3 feet ¾ inches (or 3.75 feet)

You can calculate the volume using the formula for the volume of a rectangular prism, which is length × width × height.

First, calculate the volume in cubic feet:

• Volume = 2 feet × 2.5 feet × 3.75 feet = 18.75 cubic feet

Next, to convert cubic feet to gallons, you can use the conversion factor where 1 cubic foot is approximately 7.48 gallons. Therefore:

• Volume in gallons = 18.75 cubic feet × 7.48 gallons/cubic foot ≈ 140.4 gallons

This calculation shows that the grease interceptor holds approximately 140 gallons, which falls within the range of 140 to 142 gallons. Hence, the correct answer is that it approximately contains 140-142 gallons of water.
