Answer:
Step-by-step explanation:
If you want the surface area of a rectangular prism, then you'll use a formula resembling this:
A = 2(area of end) + 2(area of top) + 2 (area of side).
Example: suppose the dimensions of the prism are 3 in by 5 in by 8 in.
Then the total surface area is:
A = 2(3*5) + 2(3*8) + 2(5*8) square inches, or 2(15) + 2(48) + 2(40) sq in, or
A = 30 + 96 + 80 sq in, or A = 206 sq in

[ Explanation ]
W - Width
L - Length
H - Height
Area = 2 Multiplied By...Width * Length + Height * Length + Height * Width
==============================
Example Problem:
Rectangle:
Width - 6
Height - 2
Length 3
Plug Numbers Into Equation:
2(6 * 3 + 2 * 3 + 6 * 2)
Solve
6 * 3 = 18
2 * 3 = 6
6 * 2 = 12
Add
18 + 6 + 12 = 32
Multiply
36 * 2 = 72
Surface Area = 72 [tex]Units^{2}[/tex]
