  4. KC 1

  5. Volume of a Rectangular Prism Find the volume of the rectangular prism. V = ℓwh Volume of a rectangular prism V = 4● 3 ● 2 Replace ℓ with 4, w with 3, and h with 2. V = 24 Multiply. Answer: 24 cm3 Example 1

  6. A B C D Find the volume of the rectangular prism. A. 20 in3 B. 100 in3 C. 240 in3 D. 960 in3 Example 1

  7. GAMES The manufacturer of the game Bugs of Planet Zykon uses the box shown. If the manufacturer increases the length of the box to 10 inches, how much will the box’s volume increase? Volume of original box V = ℓwh Volume of a rectangular prism V = 8.5 ● 6 ● 4 Replace ℓ with 8.5, w with 6, and h with 4. V = 204 Multiply. Example 2

  8. Volume of new box V = ℓwh Volume of a rectangular prism V = 10 ● 6 ● 4 Replace ℓ with 10, w with 6, and h with 4. V = 240 Multiply. The difference in volume between the new box and the original box is 240 – 204 or 36 cubic inches. Answer: The box’s volume will increase by 36 in3. Example 2
