Frustum

To all my friends, I hope you got as much as you wanted for your Groundhog's Day presents. Me, I got a frustum.

Which was cool.

Then I realized that the picnic table on the lawn was equally covered but even more cool, if you can believe it.

An eight-sided pyramidal frustum? I don't even know, but Mrs. Curmudgeon loves it. Math Teachers. What can you say?
