Question

If each edge of a cube is doubled , then find how many times will its volume increase?​

Answer 1

Answer:

8 times

Step-by-step explanation:

Let the initial edge of the cube be 'l' cm.

If each edge of the cube is doubled, then it becomes '2l' cm.

Initial volume of the cube = l³

New volume = (2l)³ = 8 × l³

Ratio = l³: 8 l³= 1:8

Thus, the volume increases by 8 times.
