if the surface area of a cube is 486 cm sq, find its volume?

**surface area of cube = 6 X (s) ^{2}**

**where "s" is the side of the cube.**

**therefore,**

**6s ^{2} = 486**

**hence, s ^{2} = 81**

**=> s = 9 cm**

**therefore volume = (s) ^{3 }{as all the dimensions have same length}**

**= (9) ^{3}**

**= 729 cm ^{3}**

**hope it helps!!**

**cheers!!!**

**thumbs up plzz...**
