Over 1.2 million square feet of travertine stone from Italy was used to construct the Getty Museum. It was mined in large slabs that measured 6 meters high, 12 meters wide, and 2 meters deep. Find the surface area of one of these slabs.
The surface area is the sum of the areas of each face of the slab. We have two faces whose dimensions are 12 by 2; two faces whose dimensions are 6 by 2; and two faces whose dimensions are 12 by 6.
