There are 28 digits in one cubit. The ancient Egyptians had their own system for measuring length based on body lengths. A digit was based on the width of one finger (about 19 mm). A cubit was the distance measured from the elbow to the tips of the fingers, and this equalled 28 digits.
Use a ruler to measure a digit and a cubit on yourself. How many of your digits make one cubit? How close is it to 28? Take measurements from a number of different people. How close are they to 28?
= 2 x 2 x 7
= 2 x 14
= 4 x 7
= 1 + 2 + 3 + 4 + 5 + 6 + 7
