One, if it is glass--
a piece of a very thick cake would be in the shape of a triangular prism so if you take a thick cake and cut it into regular sized pieces, the shapes of the pieces would be triangular prism

4 triangles make 1 hexagon. (easy way to find out how many triangles there are in a polygon- take number of sides of the polygon, subtract 2 from it, that's your answer!)

Honey, those Aztecs weren't messing around when it came to building pyramids. It took them anywhere from a few months to several years to construct those bad boys, depending on the size and complexity. So, grab a snack and get comfy, 'cause building a pyramid was definitely a long-term project for those ancient folks.

The construction of the Egyptian pyramids varied in duration, depending on the size and complexity of the pyramid. Larger pyramids such as the Great Pyramid of Giza could take around 20 years to build, while smaller pyramids could be completed in a few years.
Rectangular prisms have two rectangles at each base. Take four lines and connect the four corners perpendicularly of the two rectangles to make a rectangular prism. Rectangular pyrimads only have one rectangle base. Draw four lines from the four corners of the rectangle and make those four lines meet at one point. The way these two are alike is that they both had rectangular bases.
