Question

If every side of a cube of volume V is doubled, its volume becomes kV, then the value of k is....

Answer 1

the volume of k is eqals to v

Answer 2

Answer:

∴KV=8V⇒K=8

Step-by-step explanation:

Let the side of cube is a cm

then volume of cube=V =a^3 cm^3

If side is doubled then side =2a

Then volume of new cube =KV=(2a) ^3 =8a ^3 cm ^3

∴KV=8V⇒K=8.
