Question

fill in the blank under each figure below. tetrahedron triangular prism cube number of faces = number of edges = number of vertices =

Explanation:

Step1: Recall tetrahedron properties

A tetrahedron has 4 triangular faces. So number of faces of tetrahedron = 4.

Step2: Recall triangular - prism properties

A triangular prism has 2 triangular bases and 3 rectangular lateral faces. So number of edges = 9.

Step3: Recall cube properties

A cube has 8 vertices.

Answer:

Number of faces of tetrahedron: 4
Number of edges of triangular prism: 9
Number of vertices of cube: 8
