This document presents a song about 2D and 3D shapes. It lists various flat 2D shapes like circles, triangles, pentagons, rectangles, squares, and hexagons along with their width and height. It then lists various solid 3D shapes like pentagonal prisms, cuboids, triangular prisms, hexagonal prisms, and cylinders, providing their height, width, and depth. The document was created by four students in 2016 to teach about 2D and 3D shapes through a song.
