Question

you work for a wart remover company. the trailer of one of your dump trucks is 10 feet wide,15 feet long,and 6.5feet high.if a ton of debris equal 200 cubic feet,how many trucks are needed to cart away 45 tons of debris from from a demolition site?

Answer 1

oook

so find total volume capacity of one truck
volume=lenght times widht times height
volume=10 times 15 times 6.5
volume=975 cubic feet per truck

ok, find volume needed for 45 tons

200cubic feet=1ton
times 45 both sides
9000cubic feet=45 tons

ok

n=number of trucks
n times capacity per truck=9000 cubic feet
n times 975=9000
divide both sides by 975
n=9.2whaterver
you can't get 0.2 truck
you have to take all the debris
round up (even though 2<5)
10 trucks
