Building Pyramids
February 21, 2018
Our task today was to build pyramids that have a volume of 300cm^3. We needed to figure out dimensions, and make a net, then cut it out of old file folders and then we tested them to see if they matched the measurements we wanted.
Planning is important! So is measuring.
Some of our pyramids were perfect! Others ended up being too short.
Those groups mixed up the prism height and the slant height. We can calculate the slant height using the pythagorean theorem.
It’s neat to see the different variety of pyramids that all have the same volume.
It was also fun to work through the challenge as part of a team.
