To solve this, we must know the formula for surface area of a rectangular prism. The formula solves for 3 of the faces, and then multiplies by 2, because in a rectangular prism, 2 opposite sides will always be equal.
The formula is 2(wl+hl+hw)
Now all we have to do is substitute in our values and solve.
2(wl+hl+hw)=
2(12*11+11*11+11*12)=
2(385)=
770=
Using the math above, we can see that the correct answer is A. 770 square cm.
Part A. Yes, because y=f(x)=x⁵.
Part B. f(4)=2(4)+12=8+12=20.
