## 10.3 Three-Dimensional Figures

Pg:534

## Prisma solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms. | ## Cone a solid or hollow object that tapers from a circular or roughly circular base to a point. | ## Pyramid A solid object where: The base is a polygon (a straight-sided flat shape) The sides are triangles which meet at the top (the apex). It is a polyhedron. |

## Prism

## Cylinder a solid geometric figure with straight parallel sides and a circular or oval cross section. | ## Sphere a round solid figure, or its surface, with every point on its surface equidistant from its center. |

## 10.4 Surface Areas of Prisms and Cylinders

**Words to know:**

Net (two-dimensional pattern that forms a solid when folded)

Surface Area (the sum of the areas of its faces)

Pg:542

## 10.5 Surface Areas of Pyramids and Cones

**Words to know:**

Slant height (the height of a lateral face, that is any face thats not a base)

Pg:548

## 10.6 Volume of Prisms and Cylinders

**Words to know:**

Volume (measure of the amount of space a solid occupies)
