Math 3 - Ch. 9 L1 Lesson

Two types of 3-D solids are prisms and pyramids.

​

3-D Solids

​A prism is a solid with 2 bases and a pyramid is a solid with 1 base.

Multiple Choice

What is the main difference between Prisms and Pyramids?

• A prism has 2 bases and a pyramid has 1 base.

• A prism has to have all 90 degree sides and a pyramid doesn't

• A prism must have a least one curved line and a pyramid doesn't

• A prism must be 3-d but a pyramid shouldn't

• Face

Multiple Choice

The arrow is pointing to a ________.

• Edge
• Vertice
• Face

SPHERE

One face, no edge, no vertice

CYLINDER

3 FACES. 2 EDGES AND 0 VERTEX

PYRAMID

A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex. A pyramid is formed by connecting the bases to an apex. Each edge of the base is connected to the apex, and forms the triangular face, called the lateral face. If a pyramid has an n-sided base, then it has n+1 faces, n+1 vertices, and 2n edges.

PRISM

It has identical ends (polygonal) and flat faces.

It has the same cross-section all along its length.

CONE

A funnel is shaped like a cone. An ice cream is scooped in a conical pastry. The barriers we see on roads are also conical. The birthday hats are conical in shape.
