How many trucks are needed to cart away 45 tons of debris from a demolition site?

Question

The trailer of one of your dump trucks is 10 feet wide, 15 feet long, and 6.5 feet high. A ton of debris is equals 200 cubic feet.

Answer 1

V = lwh

V = 15(10)(6.5)

V = 975 ft³

 

975 ft³ (1 ton/200 ft³) = 4.875 tons/truck

4.875 tons (45) = 219.375 = 220 trucks
