Length (cm) x Width (cm) x Height (cm) / 1000 = Volume in litres
Given the dimensions of the fish tank as 48 cm in length, 15 cm in width, and 12 cm in height, we can calculate the volume as follows:
48 cm x 15 cm x 12 cm / 1000 = 86.4 litres
Therefore, the fish tank with the dimensions of 48x15x12 can hold approximately 86.4 litres of water.
