One aquarium is 12 inches long another is 15 inches long and a third is 18 inches long they are all 18 inches deep and 12 inches wide which aquarium can hold exactly 3240 cubic inches of water

Hello!



The aquarium that is 15 inches long, 18 inches deep, and 12 inches wide can hold exactly 3240 cm^3 of water.



To fine the volume of the tank, we must use this formula:

V = l × d × w

We know that all three aquariums are 18 in deep and 12 in wide, but we do not know the length.

We've been given three lengths (12 in, 15 in, and 18 in). Substitute and find out which one will give us a volume of 3,240 cm^3:

V = 12 × 18 × 12

V = 2,592

The first length won't work.

V = 12 × 18 × 15

V = 3,240
