The Shape of the Coins
When Rakesh puts the 10 one rupee coins of similar kind exactly one on the other, the shape he will get finally is a cylinder.
Explanation
- The shape of a coin is similar to a circle. When Rakesh puts the coins one on top of the other, the circular shape of each coin will be visible.
- As he continues to stack the coins, the circular shape will be maintained, and the coins will form a cylindrical shape.
- A cylinder is a three-dimensional shape that has two circular bases and a curved surface connecting the bases. When Rakesh stacks the coins, the circular bases of the coins will form the bases of the cylinder, and the curved sides of the coins will form the curved surface of the cylinder.
- The height of the cylinder will be equal to the thickness of a single coin, as Rakesh is putting the coins exactly one on top of the other.
- Since all the coins are of the same kind and have the same dimensions, the resulting cylinder will have a uniform shape throughout.
Visual Representation
To visually represent the shape of the coins, we can imagine a stack of 10 circular coins placed one on top of the other, forming a cylinder. The top and bottom of the cylinder will be circular, and the sides will be curved.
Conclusion
Therefore, when Rakesh puts the 10 one rupee coins of similar kind exactly one on top of the other, he will get a cylindrical shape.
