Question

What is the change in TSA of a cuboid if ‘a’ is doubled, ‘b’ tripled, ‘c’ halved?

Answer 1

Step-by-step explanation:

Length of cuboid=l

Breadth of cuboid=b

Height of cuboid=h

Volume=lbh

Length of new cuboid =2l

Breadth of new cuboid=21b

Height of new cuboid=h

Volume=2l×2b×h

Required ratio=lbh:2l×21b×h

=lbh

⇒ ratio=Volume of new cuboidVolume of original cuboid=lbhlbh=1

∴ ratio is 1⇒volume is the same. No change.
