Question

If we increase the length of a cuboid to twice its initial length, what is the volume of the new cuboid?

• A. Twice the initial volume
• B. Same as of that of the initial volume
• C. Thrice the initial volume
• D. Half of the initial volume

Answer 1

The correct option is A

Twice the initial volume

Let length, breadth, and height of cuboid be $l,b$ and $h$ respectively.

Volume of cuboid $=lbh$

Now, length of cuboid $=2l$

Volume of the new cuboid $=2l\times b\times h=2lbh$

Hence, the volume of the new cuboid is twice the volume of the old cuboid.
