How many gallons does a aquarium that's 4x2x1.5 feet hold?
To calculate the volume of an aquarium measuring 4 feet long, 2 feet wide, and 1.5 feet high, you multiply the dimensions: 4 x 2 x 1.5 = 12 cubic feet. Since there are 7.48 gallons in a cubic foot, you multiply 12 by 7.48, resulting in approximately 89.76 gallons. Therefore, the aquarium holds about 90 gallons.
