T.L. and Quina plan to add a 6-inch thick layer of gravel to their driveway. The driveway is 15 yards long and 3 yards wide. What volume of gravel in cubic yards is required? Assume the driveway layer is in the shape of a rectangular slab.
Answer provided by our tutors
1 yd = 36 in
1 in = 1/36 yd
6 in = 6/36 yd
6 in = 1/6 yd
V = 15*3*(1/6)
V = 6.5 yd^3
The volume of the required gravel is 6.5 yd^3.
