Three-dimensional Shapes (3D)

Three-dimensional Shapes (3D). These shapes are solid or hollow, you could hold them in your hand. They have three dimensions: length, width and height. Solid. A shape you can hold (3D). A solid has length, width and height. Examples: Cube Cylinder Sphere Cone Prism. Surface.

3-Dimensional Figures

3-Dimensional Figures. Sphere- a solid that has a boundary consisting of all points at a given distance from a point that is the center. Sphere. Cone- a solid figure that slopes evenly to a point from a circular base. Cones. Rectangular prism- a 3-dimensional figure with six rectangular faces.

Volume of prisms

Volume of prisms. Volume of prisms. We can think of a prism as a polygon that has been pulled into three dimensions. This creates two congruent bases and rectangular faces between them. Volume of prisms.

EXAMPLE 1

Classify the solid. Tell whether it is a polyhedron. EXAMPLE 1. Classifying Solids. The solid has two congruent circular bases that lie in parallel planes, so it is a cylinder. It is not a polyhedron, because circles are not polygons.

Introduction to 3D shapes

Introduction to 3D shapes. What is a 3D shape?. Any shape that is not flat and has volume. How do you know the name of the shape?. By looking at the properties of the shape. E.g. a cuboid has 6 faces and 8 vertices. E.g. a triangular prism has 3 rectangular faces and 2 triangular faces.
