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
