Question

If a pile of a deson of Buttons has a height of 2cm 4mm, what is the thickness of one to button.​

Answer 1

The thickness of one button will be 2mm

• According to this question, a pile of a dozen buttons has a height of 2cm 4mm. A dozen means 12, hence, 12 buttons has a height of 2cm 4mm.

* N.B: We convert the height of the 12 buttons to same unit (mm)

• Since 1cm = 10mm

Then, 2cm = 2 × 10 = 20mm

20mm + 4mm = 24mm

• That is, twelve buttons (a dozen) has a thickness of 24mm, one button will therefore, be:

24/12 = 2mm thick

Hence, one button is 2mm thick.
