Project #14
Domain: Measurement and Data
Standards:
4.MD.2 Use the four operations to solve word problems involving distances, intervals of time, liquid
volumes, masses of objects, and money, including problems involving simple fractions or decimals, and
problems that require expressing measurements given in a larger unit in terms of a smaller unit.
Represent measurement quantities using diagrams such as number line diagrams that feature a
measurement scale.
Directions:
1. Read the background information about cubits used
in building pyramids.
Cubit Craze!
The ancient Egyptians used a measurement called a cubit to build the pyramids. A cubit was the
distance from the bent elbow to the end of the middle finger.
Using your own self as a measurement, find out how many inches in a cubit.
2. Use the internet (with supervision), math text book, or reference book for help to find out how to
convert cubits to inches. Then, use the information you found to solve the second part of the
problem below.
If a pyramid is 100 cubits long, about how many inches is that?
How many feet?
