Question

Josie has a small fish tank shaped like a rectangular prism. Her fish tank measures 7 inches tall and 9 inches wide. If Josie's fish tank holds 378 cubic inches of water, how many inches long is it?

Answer 1

Answer:6

Step-by-step explanation:

If we know that the formula of a rectangular prism is length * width * height, and we know the height and width are 7 and 9, the length is the only thing that is left. The volume is 378, and so now we have:

length * 7 * 9 = 378. Dividing the 9 and 7, we get 378/(9*7). The length is 6.
