A fish tank is 20 inches long 20 inches deep and 10 inches high. what is the maximum volume of water

Convert 20 inches to centimeters, and then calculate the volume of the water in the tank, then we can convert the volume in cm^3 to liters. Here's the formula: Vol = L x W x H = 50.8 cm x 50.8 cm x 25.4 cm = 65548 cm^3

65548 cm^3 x (1 L x 1000 cm^3) = 65.5 liters
