Answer 2

Answer:

Lateral surface area is the area of the 4 ‘walls' of the cube all of which are squares of side = 6 cms (given). Therefore the lateral surface area = 4 a^2 = 4 x 6 x 6 = 144 cm^2.

Total surface area is the area of the 4 ‘walls' of the cube together with the top and base of the cube, all of which are squares of side = 6 cms (given). Therefore the total surface area = 6 a^2 = 6 x 6 x 6 = 216 cm^2.
