Miranda is painting the outside of a box that is in the shape of a rectangular prism. The
length of the box is 15 cm, the width is 6 cm, and the height is 5 cm.
What is the surface area of this box?
A. 195 cm
B. 315 cm
C. 390 cm
D. 450 cm?
I believe the answer would be C. 390. The equation to find surface area of a rectangular prism is 2(wl+hl+hw). Plug in the correct numbers and you get 390.
