Question

An aquarium can be modeled as a right rectangular prism. Its dimensions are 20 in by 8 in by 7 in. If the aquarium contains 302 cubic inches of water, what percent is full? Round your answer to the nearest whole number if necessary.

Answer 1

Approximately 27%

Explanation:

To find the percent that the aquarium is full, we need to compare the volume of water in the aquarium to the total volume of the aquarium.

The volume of a right rectangular prism can be found by multiplying its length, width, and height. In this case, the dimensions of the aquarium are 20 in by 8 in by 7 in. So, the volume of the aquarium is:

20 in * 8 in * 7 in = 1120 cubic inches

Now, we can find the percent that the aquarium is full by dividing the volume of water by the total volume of the aquarium and then multiplying by 100.

302 cubic inches / 1120 cubic inches = 0.2696

To convert this to a percentage, we multiply by 100:

0.2696 * 100 = 26.96%

Rounding to the nearest whole number, the aquarium is approximately 27% full.
