Lesson Surface Area Prisms

What is the total surface area formula for a prism?

• SA = 2πrh +2πr²

• SA = Ph + 2B

• SA = πrl + πr²

• SA = ½Pl + B

In surface area formulas, what does B represent?

• bottom

• perimeter of the base

• area of the base

• base

In the formula Ph + 2B, why are you multiplying 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.

What does "P" stand for in the surface area formulas?

• Perimeter of the area
• Parallel
• Perimeter of the Base
• Pi

In the formula Ph + 2B, what does h stand for?

• the height of the base

• the height of the prism
