Question

the dimensions of a cuboid are doubled. how many times does the volume become

Answer 1

assume the dimensions of the cuboid are x,y and z

volume of a cube= x * y * z

its volume would be xyz

the new dimensions become 2x,2y and 2z

the new volume equals 8xyz

 therefore the new volume is 8 times the older one

Answer 2

volume will increase by 8 times
since,
length be x
breadth be y
height be z
so new length breadth and height will be
2x,2y and 2z respectively
volume will be xyz
increased volume will be 8xyz
volume become 8 times
