The surface area for a rectangular prism with a square base is sa=2s2+4sh. what is the surface area if s=2 and h=4?

We know that
[surface area for a rectangular prism with a square base ]=2*s²+4*s*h

2*s²> Is the surface area of the bases
4*s*h---> is the lateral area
s=2 units
h=4 units

[surface area for a rectangular prism with a square base ]=2*2²+4*2*4
surface area=8+32> 40 units²

the answer is
40 units²

Will the shortest side will, the one with second side.
