Ray wants the larger of two aquariums. One aquarium has a base of 20 in. by 20 in. and a height of 18 in. The other aquarium has a base of 40 in. by 12 in. and a height of 12 in.
Which aquarium is larger? By how much?
Answer (3)
To find these measurements, just multiply.
20 x 20 = 400 x 18 = 7200 in. 40 x 12 = 480 x 12 = 5760 in.
So, the first aquarium is larger. Subtract to find the difference.
7200 - 5760 = 1440 in.
the first A. 20 x 20 x 18= 7200 the second A 40 x 12 x 12= 5670
the first is bigger by 1530
The first aquarium has a volume of 7200 in³, while the second aquarium has a volume of 5760 in³. Therefore, the first aquarium is larger by 1440 in³.
