Quizplus · Accepted Answer

The volume of a box is calculated by multiplying its length, width, and depth. Here, the length = 3 in. = 75 mm The width = 2 in. = 50 mm The depth = 2.5 in. = 65 mm Therefore, the volume = length x width x depth = 75 mm x 50 mm x 65 mm = 12,187.5 cubic millimeters. Converting into inches, we get 12,187.5 / 25.4^3 = 12.5 cubic inches. Hence, the correct option is (C) 12.5 in.³ (205 cm³).
