Basics of Surface Area of Prisms

How much paper is needed to wrap the candy bar?

• 156 inches ²

• 126 inches ²

• 130 inches ²

• 155 inches ²

Match the following. S.A = Ph + 2B

B = 180

• 60

• Height of the solid

• 1,260

• Surface Area

• 15

• Perimeter of the base

In the equation: SA = Ph + 2B, what does the B stand for?

• base

• area of base

In the equation:  SA = Ph + 2B, why are you multiplying B by 2?

• Just because it's the formula.

• It is multiplying B by 2 because there are two bases.

• It's just the number 2.
