Actually Welcome to the Concept of the Surface areas and the Volumes.

Now, we know that, a cube has 6 faces that are all square.

so some of the formulae of the CUBE are as follows:-

1.) Total Surface area = 6*(side)^2

2.) Lateral Surface area = 4*(side)^2

3.) Volume = (side) ^3

so we apply here, the first formula and get as,

=> side = 40 cm

=> T. S. A = 6*(40)^2

=> 6*(1600)

=> 9600 cm^2

⭐so the total surface area is 9600 cm^2
