I opened a pen package today and was going to save the white board inside for signs, then realized they had little folds in the ends and the middle. Curiosity took over and I folded them, to find that they make a perfect little pyramid!
The shape is a triangular prism. A Pyramid has sides that are triangles, and only one base. This shape has triangular bases (two of them, even if it is not sitting on the base), and rectangular faces/sides. An ordinary box is a rectangular prism, because the bases are rectangles. Toblerone chocolate comes in a triangular prism box. The Pyramids are called that because that is the shape they are-- pyramids.
The math teacher in me couldn't resist this.
Am not being a smart Alec and mean this in all sincerity about the excellent Math instruction. In all fairness, 'visually' it depends on the angle one is viewing/thinking/associating ;-)
Sandra, what clever ideas you came up with and glad to see you are thinking outside of the box and giving others inspiration :-)
I am thinking of using your idea by gluing a magnet on one side, placing it on my refrigerator door and then sliding a mechanical pencil from that same package for easy access to write items on the grocery list :-) Thanks a bunch!
Hey, I did great in fractions and decimals, but you are right! Thanks, and no, I am not offended. Heck, I gently correct people on ebay all the time. I collect snails, and when I am searching, I find so many people think a turtle is a snail, so I am always helping the "snail challenged" sellers.
