Answer:
22ft^2


l=1ft,
w=3ft, and
h=2ft


SA = 2lw + 2lh + 2wh = (2(1)(3)) + (2(1)(2)) + (2(3)(2)) = 6 + 4 + 12 = 22 ft^2

When solving you have to use PEDMAS/BEDMAS/PEMDAS (they all mean the same thing), which means that you'd multiply the terms in the brackets before adding them together.

The picture attached herewith depicts the way you'd draw the rectangular prism if need be.

Explanation:

Here is equation
