Question

help me friends to solve this question if length of each edge of a cube is tripled what will be the change in its volume

Answer 1

it's volume also gets tripled
sides of cube are equal all

Answer 2

if length of each edge of a cube is tripled

let the edge of the cube be a
age is tripled=3a

then
volume of cube = a ^3
=(3a)^3
=9a^3
=9×a^3


so if edge of a cube is tripled then its volume will increase 9 times.
