A tank has a square base of 16 cm. If its is 20 cm high how much liquid woul it contain?

To calculate the volume of liquid that a tank with a square base can contain, we need to calculate the volume of the tank. The volume (V) of a rectangular prism (which includes tanks with square bases) is given by the formula:

V = length × width × height

Since the tank has a square base, the length and width are the same and are both 16 cm. The height of the tank is 20 cm.

V = 16 cm × 16 cm × 20 cm
V = 256 cm² × 20 cm
V = 5120 cm³

The tank would contain 5,120 cubic centimeters (cm³) of liquid. To convert this to liters (since liquids are often measured in liters), we use the fact that 1 liter equals 1,000 cubic centimeters:

5,120 cm³ ÷ 1,000 cm³/L = 5.12 L

The tank would contain 5.12 liters of liquid.
