PLZ HELP ME! Find the surface area of this rectangular prism. Write an equation and show your work.

9 x 3 = 27, 27 x 2 = 54

4 x 3 = 12, 12 x 2 = 24

9 x 4 = 36, 36 x 2 = 72

Add given areas:

54 + 24 + 72 = 150 cm^2 is your answer.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
