How many milliters of water can the fish tank hold?

To determine how many milliliters of water a fish tank can hold, you need to know the tank's dimensions (length, width, and height) and then use the formula for volume. For example, if a tank measures 60 cm long, 30 cm wide, and 30 cm high, the volume would be 60 x 30 x 30 = 54,000 cm³. Since 1 cm³ is equivalent to 1 mL, this tank would hold 54,000 mL of water.
