3d Shapes and Nets

What is a net in relation to 3-D shapes?

• A net is a three-dimensional model of a shape.

• A net is a two-dimensional representation of a 3-D shape that can be folded to form the shape.

• A net is a type of material used to cover shapes.

• A net is a mathematical formula used to calculate the volume of a shape.

What is the difference between a triangular prism and a triangular pyramid?

• A triangular prism has one triangular base and three triangular faces.

• A triangular prism has two triangular bases, while a triangular pyramid has one triangular base and three triangular faces.

• A triangular prism has three triangular bases, while a triangular pyramid has two triangular bases.

• A triangular prism and a triangular pyramid are the same shape.

What is a rectangular pyramid?

• A 3-D shape with a rectangular base and triangular faces that meet at a point (the apex).

• A flat shape with four equal sides and no height.

• A 3-D shape with a circular base and a single vertex at the top.

What is the relationship between the number of faces, edges, and vertices in a 3-D shape?

• Faces + Vertices - Edges = 2

• Faces - Edges + Vertices = 3
