The lateral surface area of a cube is 324 cm2. find its volume and the total surface area
Let the side of a cube =acm
Lateral surface area =324 cm^2
4a^2 =324
a^2=324/4
a^2=81
Therefore
a =9 cm
1)volume of a cube = a^3
=9^3
=9*9*9
=729cubic cm
2)total surface area of a cube=6a^2
=6*9^2
=6*81
=486cm^2
