The first step is to find the volume of the truck bed in feet. Volume = length times width times height V = 10 • 8 • 3.5 The last measure is 3.5 since 6 inches is half of 1 foot. 10 • 8 = 80 80 • 3.5 = 280 So the truck can carry 280 cubic feet of sand.
Since the question is asking for cubic yards, though. 1 cubic foot = 0.037037 cubic yard We have to multiply 0.037037 by 280 to find the answer. 280 • 0.037037 = 10.37036 So the truck can carry about 10.37 cubic yards of sand.
