How big is that Pyramid?

The Great Pyramid of Giza was built some 45000 years ago, and for nearly 4,000 years was the tallest building in the World.  How big is our school compared to this fabled structure? See how many of the following ways to compare size you can complete.

The size of the Great Pyramid of Giza can be found from this Link.   Remember to show your work!

1.One way to compare is to measure the base area of Bruce and the Great Pyramid. Area is Width X Length

2.Another Way to measure is to compare the heights of the two structures. No climbing the school to find the height!!! Have someone stand beside the school estimate how many of them it would take to reach the top of the school.

3. Perhaps the most accurate way to measure the size is by comparing the volume.  Width X Length X Height/3 gives us the volume of Bruce Middle School. The volume of a pyramid is  Width X Length X Height /3.


Answers to above

Area of school and the pyramid

Bruce school 51,430 sq. ft
Height of main building, about 17 ft

Area of pyramid 586,500 sq ft
Height 481ft

11 Bruce’s for the base of the Great Pyramid

29 Bruce’s for the height of the Great Pyramid

Volume of the Great Pyramid
Area times Height divided by 3 = 94035500

Volume of Bruce = 291436

Difference between the two in area is that 323 Bruces would make the volume of the Great Pyramid.
