Question

24 coins are placed one upon another and their total thickness is recorded by half meter scale. The thickness is found to be 4.8 cm. Find the thickness of each coin in mm. [2mm]

Answer 1

Given:

24 coins are placed one upon another and their total thickness is recorded by half meter scale. The thickness is found to be 4.8 cm.

To find:

Thickness of each coin

Calculation:

Let thickness of each coin be x cm

So, thickness of the whole stack = 24x cm

As per the half-metre scale , the total thickness is 4.8 cm

$\therefore \: \: 24x = 4.8$

$= > \: \: x = \dfrac{4.8}{24}$

$= > \: \: x = 0.2 \: cm$

$= > \: \: x = 2 \: mm$

Hence the thickness of each coin is 2 mm.
