Question

A marble pillar in the shape of a square prism has a length and width of 2.5 feet and a height of 12 feet. The pillar weighs 12,000 pounds. How many pounds per cubic foot is the density of the marble?

Answer 1

Length x Width x Height = cubic feet


2.5 ft x 2.5 ft x 12 ft = 75 ft^3


Take the total weight of 12,000 lbs and divide by the cubic feet of 75


12,000 lbs/75 ft^3 = 160 lbs/ft^3


Hope this helps!!!
