total surface area of a cube is 6a^2
given total surface area = 864 sq m
6a^2 = 864 sq m
a^2 = 864/6 sq m
a^2 = 144 sq m
a = √144
a = 12 m
edge of cube = 12m
given total surface area = 864 sq m
6a^2 = 864 sq m
a^2 = 864/6 sq m
a^2 = 144 sq m
a = √144
a = 12 m
edge of cube = 12m

Total surface area = 6a^2
864 = 6a^2
864/6 = a^2
144 = a^2
√144 = a
12 = a
Hence the edge of cube is 12m
Hope it helped u:-)
