• The sum of all the areas of all the shapes that cover the surface of the object.
• Something Mrs. MacGregor made up?
• Surface area is what you get when you boil unicorn tears. 

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.

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

• Perimeter
• Parallel
• Perimeter of the Base
• Pi
