Question

the lateral surface area of a cube is 36m² find the total surface area​

Answer 1

Here the value of the lateral surface area is given to be 36m²

We will use this information to find the measure of side of the cube

Lateral surface area = 4 ( side ) ²

                           36  = 4 ( side ) ²

                   ( side ) ² = 36 /4

                    ( side ) ² = 9

                         side   = 3

Now, we will apply the formula for the total surface area of the cube

Total surface area = 6 ( side ) ²

                               = 6 × (3)²

                                 = 6 × 9

                                 = 54

Hence, the total surface area of the cube will be 54 m²
