Find the surface area of a cube whose edge is
(i) 1.2 m
(ii) 27 cm
(iii) 3 cm
(iv) 6 m
(v) 2.1 m
(i) We have,
Edge of cube = 1.2 m
Surface area of cube = 
(ii) We have,
Edge of cube = 27 cm
Surface area of cube = 
(iii) We have,
Edge of cube = 3 cm
Surface area of cube = 
(iv) We have,
Edge of cube = 6 m
Surface area of cube = 
(v) We have,
Edge of cube = 2.1 m
Surface area of cube =
