Problem of the Week
for Friday, December 5

 

Can you figure out a way to use a sheet of 8 1/2 by 11 paper to measure exactly 6 inches?

Josh's Solution:

Yes!! Just follow these steps:

1. Fold one corner so that it makes a triangle and a 2 1/2 inch bar at the top.

2. Take the 2 1/2 inch strip and fold it over the triangle.
This measurement is 6 inches because you first have 8 1/2 inches , then by folding over the 2 1/2 inch strip it subtracts 2 1/2 inches, leaving six inches!
