Answer 2

Answer: 108 cm^2 is the total surface area of cube

Step-by-step explanation:

Given that the lateral surface area of a cube is 64 m²

We have to find its total surface area​

Let the side of cube is a lateral surface area of cube=4a^2

4a^2=72

a^2=72/4

     =18

a^2=18

a=√18 cm

Total surface area of cube=69^2

                                      =6.(√18)^2

                                      =6x18 =108 cm^2

Hence , we get the solution 108 cm^2 is the total surface area of cube
