How much water does Brian put in the fish tank?

1 answer

The fish tank has a depth of 8 inches. Since Brian fills it half full, he would fill it with water up to 4 inches.

To calculate the amount of water Brian puts in the fish tank, we need to calculate the volume of the water in the tank.

Volume = length x width x height
Volume = 72in x 6in x 4in
Volume = 1,728 cubic inches

Therefore, Brian puts 1,728 cubic inches of water in the fish tank.
