Total surface area of a cube = 54 cm²
6a² = 54
a² = 54 / 6
a² = 9
a = √9
a = 3
Side = 3 cm Ans.

The formula to find the total surface area of a cube is 6a². We know that the area is 54 cm². Therefore, to find the length of its side, we'll have to equate the equations.
6a²=54
a²=54/6
a=√9
a=3
Hence, the length of its side is 3cm
6a²=54
a²=54/6
a=√9
a=3
Hence, the length of its side is 3cm
