A factory is filling 325 rectangular-prism tubs, like the one shown, with concrete. The manager estimates that the factory will need 1800 cubic yards of concrete to completely fill all of the tubs.

Question

A tub in the shape of a rectangular prism. It is 3 yards long, 2 yards wide, and 1 yard high.

Question
How much ,begin emphasis,more,end emphasis, concrete than the manager's estimate will the factory need to completely fill all of the tubs? Enter the answer in the box.

Answer 1

The volume of one tub is 3 yards long x 2 yards wide x 1 yard high = 6 cubic yards.

The total volume of all 325 tubs is 325 tubs x 6 cubic yards per tub = 1950 cubic yards.

Therefore, the factory will need 1950 cubic yards - 1800 cubic yards = 150 cubic yards more concrete than the manager's estimate to completely fill all of the tubs.
