Question

The surface area of a piece of paper is 527 cm2. Use the fact that 10 mm = 1 cm to convert this area to mm2. Give your answer as a number.

Answer 1

`52,700`

Explanation:

Use the fact that

`1\ cm =10\ mm,`

then

`1\ cm^2=1\ cm* 1\ cm= 10\ mm* 10\ mm=100\ mm^2`

The surface area of a piece of paper is
`527\ cm^2.` Convert it to
`mm^2:`

`527\ cm^2=527\cdot 100\ mm^2=52,700\ mm^2`
