Answer: D - A rectangular wet well that is 12 ft wide, 15 ft long, and has a liquid depth of 10 ft can hold approximately 13,464 gallons.

Solution: Volume of wet well = Length x Width x Depth

Given, 1 cubic foot (ft³) = 7.48 gallons

Volume = 15 ft x 12 ft x 10 ft

= 1,800 ft³

In gallons, 1,800 ft³ x 7.48 gallons/ ft³ = 13,464 gallons
