write and simplify a polynomial expression for the surface area of each figure.

2(2x * 2x+1) + 2(2x * x+3) + 2(2x+1 * x+3)

Use distributive property on each set of terms:

2(4x^2+2x) + 2(2x^2+6x) + 2(2x^2 +7x+3)

Use the distributive property again:

8x^2 + 4x + 4x^2 +12x + 4x^2 +14x +6

Now simplify by combining like terms:

16x^2 + 30x +6
