so you subtitute and get SA=2(2)2+4(2)(4) and get SA=8+32=40 actually the surface area is 2(s^2)+4sh and if you subitute you get the same thing
40 square units for short
To find the surface area of the rectangular prism, we used the formula S A = 2 s 2 + 4 s h . After substituting s = 2 and h = 4 , we calculated the surface area to be 40 square units.
