Answer:
The side of the cube is 10cm.
Step-by-step explanation:
Given the total surface area of the cube = 600cm²
Let the side of the cube be 'a'cm
The area of 1 side of the cube = a²
a cube has 6 faces
Hence, the total surface of the cube = 6a²
On equating, 6a² = 600
=> a² = 100
Taking square root on both sides
=> a = ± 10
=> a = 10, a = -10cm
Since length cannot be negative, a = 10
Therefore, The side of the cube is 10cm.
