Unit 6 3D Shapes and Their Properties and Nets

What is a cube? Describe its properties.

• A cube is a three-dimensional shape with six equal square faces, 12 edges, and 8 vertices.

• A cube is a two-dimensional shape with four equal sides.

• A cube has eight edges and six vertices.

• A cube is a three-dimensional shape with circular faces.

Identify a shape that has a square base and triangular faces.

• Cube

• Square pyramid

• Rectangular prism

• Tetrahedron

What is the difference between a prism and a pyramid?

• A prism is a three-dimensional shape; a pyramid is a two-dimensional shape.

• A prism has one base; a pyramid has two identical parallel bases.

• A prism has two identical parallel bases; a pyramid has one base.

• A prism can have any number of bases; a pyramid always has two bases.

List the properties of a pyramid.

• A pyramid can only have four faces and is always regular.

• A pyramid has a polygonal base, triangular faces, a single apex, a specific number of vertices and edges, and can be classified as regular or irregular based on the base.

• A pyramid has a circular base and no apex.

• A pyramid is a three-dimensional shape with only square faces.

Identify the net of a cuboid from the options given.

• The net of a cuboid is a single square that folds into the shape.

• The net of a cuboid consists of six rectangles arranged in a way that allows them to fold into the cuboid shape.

• The net of a cuboid consists of four triangles and two squares.

• The net of a cuboid includes eight rectangles arranged in a circle.
