Sunken Treasure Chest Net

Nets are multiple 2d shapes used to make a 3d shape, also known as a solid.

For the treasure chest net, you need a rectangular prism and a semicylinder.The net for a rectangular prism is two squares and four rectangles.The net for a semicylinder is one rectangle, a little wider rectangle (you need to curve it into the curved side of a semicircle or hemisphere) and two semicircles.

You need the wide side of the rectangular prism and the wide side of the semicylinder about the same length.Then you need cellar tape to connect one wide side of the rectangular prism to one wide side of the semicylinder.
Reflection:It was getting difficult to make it without a protractor, but not so difficult with a protractor. On the other hand, it was really hard to do the tabs.

However, I enjoyed making a paper treasure chest.
