Question

if a pile of a dozen of buttons has a height of 2 cm 4 mm what is the thickness of one button

Answer 1

Answer:

Explanation:

One dozen coins = 12 coins

Total height of 12 coins = 3 cm 6 mm

= 3 × 10 mm + 6 mm

= 36 mm

Therefore, thickness of one coin = 36 ÷ 12

= 3 mm

Answer 2

Thickness of one button is 0.2 cm.

Given - Thickness of a pile of buttons.

Find - Thickness of one button

Solution - As we know, 1 dozen = 12

Also, we know 1 mm = 0.1 cm

So, 4 mm = 0.1*4

4 mm = 0.4 cm

Thickness of 12 buttons = 2 cm + 0.4 cm

Thickness of 12 buttons = 2.4 cm

Thickness of 1 button = $\frac{2.4 \times 1}{12}$

Thickness of 1 button = 0.2

Hence, the thickness of 1 button is 0.2 cm.
