Question:
Two cylinders A and B are formed by folding a rectangular sheet of dimensions 20 cm × 10 cm along its length and also along its breadth respectively. Then volume of A is ________ of volume of B.
Solution:
Twice
Explanation:
Rectangular sheet dimension is 20 cm × 10 cm
When a cylinder is folded along its length, which is 20 cm, then the resultant cylinder is with height 10 cm.
Again, if a cylinder is folded along its breadth, which is 10 cm, then the resultant cylinder is with height 20 cm
When the above conditions are applied in the volume of cylinder formula,
Then we get v = 2V
