Question

It takes a hose 4 minutes to fill a rectangular aquarium 11 inches long, 12 inches wide and 13 inches tall. How long will
it take the same hose to fill an aquarium measuring 21 inches by 24 inches by 32 inches? Round your answer to the
nearest minute.

Answer 1

Answer:

38 minutes

Step-by-step explanation:

Volume of the first aquarium:

• V = lwh = 11*12*13 =  1716 in³

Volume of the second aquarium

• V = 21*24*32 = 16128 in³

The second aquarium is:

• 16128/1716 = 9.4 times bigger by volume

It will take

• 4*9.4 ≈ 38 minutes

to fill this aquarium
