The tank is in the shape of a rectangular prism. The volume of the rectangular prism is the product of its length, width and height.
Volume of rectangular prism = Length x Width x Height
Length of tank = 20.25 inches
Width of tank = 10.5 inches
Height of tank = 12.5 inches
So,
Volume of tank = 20.25 x 10.5 x 12.5 = 2657.8125 cubic inches
In order to find how much water the tank can hold, we have to convert cubic inches to liters.
1 cubic inch = 0.01639 liters approximately
So,
2657.8125 cubic inches = 0.01639 x 2657.8125 = 43.5 liters
Thus, the tank can approximately hold 43.5 liters of water.
