If each dimension of the rectangular prism is doubled, how will its total surface area change?

A rectangular prism. The length is 3 meters, width is 4 meters, and height is 2 meters.

In a rectangular prism, all six surfaces are rectangles as shown ... to length X width, (l⋅w, the surface area of the sides can be calculated by ... Total surface Area = A=2 (l+w) h+2lw=2 (lh+wh+lw). If we double all three dimensions we get: ... Doubling the dimensions makes the surface area 4 times the original ...
