Question 1
LEVEL 1
Find the number of faces, edges and vertices of the square based pyramid below.
Select the correct answer from the list below:
A: 5 faces, 8 edges and 5 vertices
B: 4 faces, 8 edges and 5 vertices
C: 5 faces, 8 edges and 4 vertices
D: 4 faces, 7 edges and 5 vertices
CORRECT ANSWER: A: 5 faces, 8 edges and 5 vertices
WORKED SOLUTION:
There are 4 triangular faces and 1 square face, so 5 in total.
There are 4 edges on the bottom and 4 diagonal edges, so 8 in total.
There are 4 vertices on the bottom, and 1 at the top, so 5 in total.
Question 2
LEVEL 1
Find the number of faces, edges and vertices of the sphere below.
Select the correct answer from the list below:
A: 1 face, 0 edges and 0 vertices
B: 1 faces, 1 edge and 0 vertices
C: 1 faces, 1 edge and 1 vertex
D: 2 faces, 1 edge and 0 vertices
CORRECT ANSWER: A: 1 face, 0 edges and 0 vertices
WORKED SOLUTION:
A sphere is made up of a single surface, so there is 1 face, 0 edges and 0 vertices
Question 3
LEVEL 1
Find the number of faces, edges and vertices of the cuboid below.
Select the correct answer from the list below:
A: 6 faces, 12 edges and 8 vertices
B: 8 faces, 12 edges and 8 vertices
C: 6 faces, 8 edges and 8 vertices
D: 6 faces, 8 edges and 4 vertices
CORRECT ANSWER: A: 6 faces, 12 edges and 8 vertices
WORKED SOLUTION:
There are 4 long faces and 2 small faces, so 6 in total.
There are 4 edges on the front, 4 edges on the back, and 2 edges on each side, so 12 in total.
There are 4 vertices on the front, and 4 vertices on the back, so 8 in total.

Select the correct answer from the list below:
A: Triangular Prism
B: Cylinder
C: Triangular Based Pyramid
D: Frustum
CORRECT ANSWER: A: Triangular Prism
WORKED SOLUTION:
This is a triangular prism.
Question 5
LEVEL 1

Select the correct answer from the list below:
A: Frustum
B: Triangular Prism
C: Triangular Based Pyramid
D: Square Based Pyramid
CORRECT ANSWER: A: Frustum
WORKED SOLUTION:
This is a Frustum.
