Question

What is the surface area of a rectangular prism that has a width of 15, length of 10 and height of 8?

Answer 1

Each of the faces of the prism is a rectangle.

The area of a rectangle is the product of its length and width.

Answer 2

On this prism, you have 2 blue rectangles, 2 purple ones, and 2 green ones.

Crank out this:
A = 2( blue + purple + green)
A = 2( wl + hl + hw) by filling in the given values for w, l, and h.
