Question

It takes a hose 5 minutes to fill a rectangular aquarium 8 inches long, 9 inches wide, and 11 inches tall. How long will it take the same hose to fill an aquarium measuring 23 inches by 25 inches by 26 inches?

Answer 1

1. Take the dimensions of the aquariums and multiply them to get the cubic inches, 

2. Take the known time and divide the cubic inches of the aquarium that was filled.

3. Take the result from step 2 and multiply it by the cubic inches of the other aquarium. That will be the time that it will take to fill the other aquarium. 

 

cubic inches = the product of the dimensions 

time to fill a cubic inch = time divided by cubic inches

time needed to fill aquarium = time to fill a cubic inch times cubic inches.
