Answer:
3 containers
Step-by-step explanation:
first, you'll need to find out the total weight of gravel in 1 truck
since one truck holds 7.5 cubic yards of gravel, and each cubic yard weighs 1.48 tons, multiply 7.5 and 1.48 to get 11.1 tons of gravel
now, divide 11.1 tons by 3.7 tons to see how many containers will be needed. And you get 3 containers
