How High?: Solution

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

How high would a million sheets of paper be?

Solution

While paper is not all the same thickness, most common paper is similar in thickness.  The easiest way to answer this question is to measure a ream (500 sheets) of paper. A ream of paper is approximately 5.2 cm thick.  Your ream may be slightly different.

2000 reams is 1 million sheets and so the height will be 2000 × 5.2cm, or 10400cm, or 104 metres high.

Another way is to divide 5.2 by 500 to get the thickness of one sheet. Then multiply the answer of that calculation by 1 million. The answer should be the same.
