Area Review
Definition: Volume is the amount of space a 3-dimensional figure takes up.
Strategy: With many shapes, you can calculate volume by multiplying the area of the base by the height.
Definition: Surface area is the area of all the surfaces of a 3-dimensional figure.
Strategy: Visualize the surface area by making "nets" that "unfold" the shape.

Volume Story Problem - Capacity And Cost
Example:
A swimming pool with dimensions shown below is filled two-thirds of the way. If the cost to fill the pool is $0.04 per cubit ft of water, how much did it cost to fill the pool two-thirds of the way?
Volume Word Problem Example
Example:
A water tank is 12 feet high, 5 feet long, and 9 feet wide. A solid metal box which is 7 feet high, 4 feet long and 5 feet wide is sitting at the bottom of the tank. What is the volume of the water in the tank?
