A contractor digs a hole for the basement of a new house that is 40 feet long and 10 1/2 feet deep. What is the width of the hole if 6,510 cubic feet of dirt are removed?

Answer 1

15.5


to find the volume of an object, you must multiply the 3d figure's dimensions which is depth, width, length. since the length, depth, and volume are found you must find the width using the expression of [L*D]/V=W
