Question 93
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 ie. a=3×a=3a
∵ Volume of the cube =a3
∴ Volume of the cube with edge tripled =(3a)3=27a3
Hence, volume is 27 times of the original volume.
