A paper manufacturer packages twelve reams of paper in a box—in three stacks of four reams. A ream of paper weighs 5 pounds and has dimensions of 8.5 inches by 11 inches by 2 inches. When filled, the weight of the paper in the box is a0 pounds.

Weight = 60 pounds.

Explanation.

There are 12 reams each weigh 5 pounds

12 x 5 = 60 pounds

If we are looking for the volume

V = L x W x H    

However we need to find the length by using the shortest thickness being the ream thickness. = 2 inches. We do this by multiplying it by 12

V = 8.5 x 11 x ( 2 x 12) = 93.5 x 24 = 2244inch^3

The weight if 5 pounds per ream we multiply this by 12 = 60
