How much water is required to fill a rectangular aquarium that is 3 feet long, 2 feet wide, and 2 feet high?

To determine how much water is required to fill a rectangular aquarium, you need to calculate the volume of the aquarium. The volume $V$ of a rectangular prism can be found using the formula:

$V = \text{length} \times \text{width} \times \text{height}$

Given the dimensions of the aquarium:

• Length ($l$) = 3 feet
• Width ($w$) = 2 feet
• Height ($h$) = 2 feet

Substitute these values into the formula:

$V = 3 \, \text{feet} \times 2 \, \text{feet} \times 2 \, \text{feet}$

$V = 3 \times 2 \times 2$

$V = 12 \, \text{cubic feet}$

Therefore, the aquarium requires 12 cubic feet of water to be filled.
