Question

Quincy Place wants to add a pool to the neighborhood. When determining the budget, Quincy Place determined that it would also be able to install a baby pool that required less than 15 cubic feet of water. Quincy Place has three different models of a baby pool to choose from.

Choice One: 5 ft. × 5 ft. × 1 ft.
Choice Two: 4 ft. × 3 ft. × 1 ft.
Choice Three: 4 ft. × 2 ft. × 2 ft.

Which of these choices is best for the baby pool? Why are the others not good choices?

Answer 1

Choice two

Explanation:

Quincy must calculate the pool’s volume in cubic feet, for each choice.

The volume is the product of the length, width and depth.

Volume = length x width x depth

Choice One: 5 ft. × 5 ft. × 1 ft. = 25 cubic feet

Choice Two: 4 ft. × 3 ft. × 1 ft. = 12 cubic feet

Choice Three: 4 ft. × 2 ft. × 2 ft. = 16 cubic feet

Which of these choices is best for the baby pool?

The best choice for the baby pool is number two, because this one requires less than 15 cubic feet of water.

Why are the others not good choices?

Because choice one and choice three are more than 15 cubic feet water, and won´t meet budget requirement.
