Find the volume of a cube whose total surface area is 486cm2
6a2 = Surface area of a cube
6a2 = 486
a2 = 486/6 = 81
a = root of 81 = 9
Therefore the side = 9 cm.
So the volume of the cube = side3
= 93
= 729 cm3
Therefore the side of the cube = 9 cm
The volume of the cube = 729 cm3
6a2 = 486
a2 = 486/6 = 81
a = root of 81 = 9
Therefore the side = 9 cm.
So the volume of the cube = side3
= 93
= 729 cm3
Therefore the side of the cube = 9 cm
The volume of the cube = 729 cm3
