MCQ
If each side of a cube is doubled, then its volume:
- AIs doubled.
- BBecomes $4$ times.
- CBecomes $6$ times.
- ✓becomes $8$ times.
✓
Answer
Correct option: D.
becomes $8$ times.
Let the original side be $' x\ ' \ cm$
$\therefore$ Original volume $= x ^3 \ cm^3$
Now,
New side $=2 x \ cm$
$\therefore$ New volume $=(2 x)^3$
$=8 x ^3 \ cm^3$
So, the volume becomes $8$ times.
$\therefore$ Original volume $= x ^3 \ cm^3$
Now,
New side $=2 x \ cm$
$\therefore$ New volume $=(2 x)^3$
$=8 x ^3 \ cm^3$
So, the volume becomes $8$ times.
