What will happen to the volume of the cube, if its edge is reduced to one-fourth?

योग

उत्तर

Let each side of the cube be a, then its volume = a3  ...[∵ Volume of a cube = (side)3]

If side reduced to one fourth = `a xx 1/4 = a/4`

Now, its volume = `(a/4)^3 = a^3/64`

Hence, new volume `1/64` times of original volume.
