If the length of each edge


If the length of each edge of a cube is tripled, what will be the change in its volume?


Let the edge of a cube be a.

If edge of the cube became tripled i.e. a = 3 x a = 3a

... Volume of the cube = a3

 ... Volume of the cube with edge tripled = (3a)3 = 27 a3

Hence, volume is 27 times of the original volume.
