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?
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
