the side of a cube is 60 cm find total surface area of cube

Answer 1

total surface area of cube=6(a×a)
6×60×60
6×3600
21600cm×cm is the total surface area of cube

Answer 2

Soln:

Total Surface area of Cube = 6a²

Given, a = 60 cm

Hence, Total surface area = 6(60)² = 6 x 3600 = 21600 cm² = 2.16 m²
