The document is about 3D shapes and their characteristics. It defines 3D shapes as solid objects with three dimensions of height, width and length, unlike 2D plane figures. It describes the key parts of prisms and pyramids, noting that prisms have two equal bases and flat quadrilateral faces, while pyramids have one base that is a polygon and triangular faces that meet at a common vertex. Finally, it introduces curved 3D shapes like cylinders, cones and spheres that have curved surfaces.

These shapes are solid.
They have three dimensions (height, width and length).
They are real life objects!

6. PRISM
Geometry 3rd
_Unit 5_3D Shapes
The two bases are equal.
The faces are flat quadrilaterals.

7. PYRAMID
Geometry 3rd
_Unit 5_3D Shapes
A pyramid has got one base. This is a polygon.
The faces are flat triangles. They meet in a common
vertex.

The name of the prims and pyramids depends on the
base's shape:
