The Solution:
The Answer
Given that the surface area of a rectangular prism with a squared base is
[tex]S\mathrm{}A=2s^2+4sh[/tex]
We are asked to find S.A if s =2 and h = 4
We shall substitute 2 for s and 4 for h in the above formula.
[tex]S.A=2(2^2)+4(2)(4)=2(4)+8(4)=8+32=40[/tex]
Therefore, the correct answer is 40.
