Vertex Of A Rectangular Prism

Iii-Dimensional Figures, or Solids

Objective

In the coming lesson, we'll review the bones three-dimensional figures and some of their backdrop.

Previously Covered

In the section in a higher place, we discussed polygons and their backdrop. We also covered how figures can be transformed; that is, they can modify location, or orientation while not changing in size or shape.

Polyhedra

A polyhedron is a 3-dimensional solid, each face of which is a polygon. Each pair of faces see at an border. The corners of the edges meet at points called vertices.

A prism is a polyhedron that has ii parallel, congruent faces called bases. The other faces are parallelograms.

This rectangular prism has six faces, twelve edges, and eight vertices.

A cube is a prism whose faces are squares.

This cube has 6 faces, twelve edges, and eight vertices.

A pyramid is a polyhedron whose base is a polygon and whose faces are triangles with a common vertex.

This triangular pyramid has four faces, vi edges, and four vertices.

This foursquare pyramid has five faces, eight edges, and five vertices.

Other 3-D Figures

These are solids that are not formed by polygons.

Question

How many more vertices than a rectangular pyramid does a rectangular prism have?

Reveal Respond

The correct answer is C. A rectangular prism has eight vertices and a rectangular pyramid has five.

Review

A polyhedron is a iii-dimensional solid where each face up is a polygon. Some examples are:
- prisms
- cubes
- pyramids
Other iii-dimensional figures (not formed by polygons) include:
- cylinders
- cones
- spheres
