Question

It takes a hose 3 minutes to fill a rectangular aquarium 9 inches long, 13 inches wide, and 14 inches tall. How long will it take the same hose to fill an aquarium measuring 21 inches by 25 inches by 35 inches?
how many minutes does it take?

Answer 1

Answer: 33.6 min

Step-by-step explanation:

Volume = L*W*H = 9 * 13 * 14 = 1638 in^3

Vol2 = 21 * 25 *35 = 18375 in^3

18375/1638 = 11.2 times bigger, so 3min * 11.2 = 33.6 minutes

Answer 2

Answer:it will take 33.65 minutes

Step-by-step explanation:

It takes a hose 3 minutes to fill a rectangular aquarium 9 inches long, 13 inches wide, and 14 inches tall. The volume of the rectangular aquarium is

Length × Width × Height.

It becomes

9 × 13 × 14 = 1638 inches^3

Therefore, it takes the hose 3 minutes to fill 1638 inches ^3

The volume of the aquarium measuring 21 inches by 25 inches by 35 inches would be

21 × 25 × 35 = 18375 inches^3

Therefore, the number of minutes it takes to fill 18375 inches^3 would be

3 × 18375 / 1638 = 33.65 minutes
