Question

answer it correctly and fast

the volume of a cuboid is 'a'cm³, if it's length, breadth and height are each doubled, the new volume will be ​

Answer 1

Answer:

8a cm^3

Step-by-step explanation:

Volume of a cuboid= lbh

If new length = 2l

new breadth =2b

new height = 2h

Then new volume = 2l×2b×2h

= 8 lbh

= 8× (volume of original cuboid)

= 8a cm^3

Answer 2

Step-by-step explanation:

volume of cuboid = lbh = a

new cuboid measures are :

2l, 2b, 2h

volume of new cuboid =2 l* 2b * 2h = 8 l b h

=8 times volume of original cuboid

= 8 a
