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?

The volume of the prism  is   2.5 * 2.5 * 12  = 75 ft^3

 

The density  =     mass / volume    =    12000 lb / 75 ft^3    =  160 lb / ft^3
