1. Volume and Surface Area 3-d shapes beware!

2. Volume Defn: what it takes to fill a 3-d solid Units are cubed ‘B’ stands for the Area of the shape of the base The only solid that doesn’t use ‘B’ is a sphere because it doesn’t have a base.

5. Example 3 There is a large cylindrical aquarium in the center of the new bank. The aquarium’s diameter is 120 inches and its height from the floor to the 12-foot ceiling. What is the approximate capacity of the aquarium in terms of feet. Round your answer to the nearest hundredth.

6. Surface area: Defn: the amount it takes to cover a 3-d solid 2 types: –Total: covers everything including the bases –Lateral: covers everything except for the bases B: area of the base P: perimeter of the base

7. Examples: Before a tissue box was opened, the opening in the top was filled with cardboard. Deanna is going to wrap and empty tissue box to use for a ballot box. How much gift-wrapping paper does Deanna need to wrap the entire tissue box?
