• A solid is a three dimensional A solid is a three dimensional figure that encloses a part of space. figure that encloses a part of space.

• Solids are classified by their bases Solids are classified by their bases and number of vertices.and number of vertices.

A cube has 6 faces, 12 edges, and 8 vertices

PrismsPrisms

• A prism is a solids with two parallel bases A prism is a solids with two parallel bases that are congruent polygonsthat are congruent polygons

When we think of pyramids we think of the Great Pyramids of Egypt.

They are actually Square Pyramids, because their base is a Square.

PyramidsPyramids

• A pyramid is a solid made of polygons. A pyramid is a solid made of polygons. The base can be any polygons and the other The base can be any polygons and the other faces are all triangles that share a common faces are all triangles that share a common vertex (also called the apex).vertex (also called the apex).

CylindersCylinders

• A cylinder is a solid with two parallel bases A cylinder is a solid with two parallel bases that are congruent circlesthat are congruent circles

Volume = Area × Height = π × r2 × h

Cones: A cone is a solid that has Cones: A cone is a solid that has one circular base and a vertexone circular base and a vertexthat is not in the same planethat is not in the same plane

SphereSphere: The set of all points that : The set of all points that are the same distance from a are the same distance from a point in the center.point in the center.
