Problema Solution
You work for a waste removal company. The trailer of one of your dump trucks is 10 feet wide, 15 feet long, and 6.5 feet high. If a ton of debris equals 200 cubic feet, how many trucks are needed to cart away 45 tons of debris from a demolition site?
Answer provided by our tutors
First we will find the volume of the dump truck:
V = 10*15*6.5
V = 975 ft^3
1 ton = 200 ft^3
45 tons = 45*200 ft^3
45 tons = 9,000 ft^3
Let x represent the number of trucks needed to carry away 45 tones of debris:
975*x = 9000
........
........
x = 9.23 trucks
Since x is an integer we conclude that there are 10 trucks needed to carry away 45 tones of debris.
