Question

find total surface area of cube whose edge is 6 CM

Answer 1

formula of total surface area is=6×side square
therefore area =6×6×6
=216cm sq.

Answer 2

Given :

Edge length of the cube (a) = 6 cm

To Find :

Total surface area of the cube

Solution :

The total surface area is equal to the sum of the areas of all the faces of the cube.

We know, a cube has six faces, hence, the total surface area of the cube will be equal to the sum of all six faces of the cube.

Let 'a' be edge length

Area of each face of the cube = a²

∴ Total surface area of the cube = 6a²

Here, a = 6 cm

Thus, Total surface area of the cube = 6 × (6)²

                                                             = 216 cm²

∴ The Total surface area of the cube is found to be 216 cm²
