Surface area of the cube = 73.5
➝ 6a² = 73.5 (a is the length of an edge of the cube)
➝ a² = 73.5/6 = 12.25
So, a = √12.25 = 3.5
Volume of the cubical tank = (3.5)³ = 42.875 m³.
Now, 1 m³ = 1000 litres
=> 42.875 m³ = 42875 litres
So, 42875 litres litres of water can be filled in a cubical tank whose surface area is 73.5 square meter.
