5. Example 1 Volume of a Prism What is the volume of a fish tank that is 4 inches long, 4 inches wide, and 6 inches tall? One Way: Use a Model Count the number of 1-inch cubes that will fill the bottom of the rectangular prism. The prism is 4 cubes long and 4 cubes wide. There are 16 cubes on the bottom.

6. Example 1 One Way: Use a Model There are 6 layers of cubes. So, there are 6 × 16 or 96 cubes. Volume of a Prism

7. Example 1 Another Way: Select and Use a Formula V = wh Formula for the volume of a rectangular prism. V = 4 × 4 × 6 = 4, w = 4, h = 6. V = 96 Multiply. Answer: The volume of the fish tank is 96 cubic inches. Volume of a Prism
