You are a driver of a dump truck with a trailer (dump bin) that is 21 feet long, 8 feet wide, and 6 feet tall Daily, you haul full

(B)17

Step-by-step explanation:

The dump truck is 21 feet long, 8 feet wide, and 6 feet tall.

Volume of the dump truck=21 X 8 X 6=1008 cubic feet

Since the dump bin can hold dirt equivalent to 1.2 times its capacity,

Volume of dirt the truck can hold=1.2 X 1008=1209.6 cubic feet

If the truck wants to haul 20,000 cubic feet of dirt.

Minimum number of trips=20000/1209.6=16.53 Trips

We round this up to 17 since there is no half trip.

Therefore, the minimum number of trips needed to haul 20,000 cubic feet of dirt is 17.
