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.
Volume of new box
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.
