Multiple Choice

Chose the correct name for this shape:

• pyramid

• prism

Prism

This shape is called triangular prism

Multiple Choice

Which of the following is the net of a cube?

• 1

• 2

• 3

Which of the following is the net of a cube?

Number 2

Multiple Select

Which 3D shape has no vertices? You can chose more than one answer

• cone

• sphere

• cylinder

• tetrahedron

• prism

Which 3D shape has no vertices?

• Vertex - corner

• 3D shapes and number of vertices - cube 8; cone 1; triangular based pyramid 4; cylinder 0; triangular prism 6; sphere 0, squared based pyramid 5

• Therefore: sphere and cylinder has no vertices

Here are some 3-D shapes

Tick each shape that has more vertices than faces

Square based pyramid - 5 faces, 5 vertices

Cuboid - 6 faces, 8 vertices

Triangular prism - 5 faces, 6 vertices

Pentagonal pyramid - 6 faces, 6 vertices

Multiple Choice

Cone

Multiple Choice

Here are some nets. Which letter is the net of the triangular prism?

• A

• B

• C

• D

Here are some nets. Which letter is the net of the triangular prism?

Correct answer: Option B (the second net on the picture)

A) squared based pyramid

B) triangular prism

C) cube

D) triangular based pyramid (tetrahedron)

Multiple Choice

3-D shapes are regular when all the faces are equal. Which 3-D shape is regular?

• Cylinder

• Cube

• Cuboid

3-D shapes are regular when all the faces are equal. Which 3-D shape is regular?

Only cube has all faces that are the same as they are squares.

Cylinder - 2 faces are circles and one is a curve face (a rectangle when opened flat)

Cuboid gas 6 rectangular faces.

Multiple Choice

If there are 9 squares on each face of on a Rubik’s Cube, how many squares are there in total?

• 15

• 27

• 36

• 54

If there are 9 squares on each face of on a Rubik’s Cube, how many squares are there in total?

A cube has 6 faces

Therefore:

6 x 9 = 54

There are 54 squares in total.

Multiple Choice

Which of the following shape is not a 3-D shape?

• Hexagonal prism

• Pentagon

• Triangular prism

• Cuboid

Which of the following shape is not a 3-D shape?

Pentagonal prism, triangular prism and cuboid (or rectangular prism) all are 3D shapes

Answer: Pentagon is not a 3D shape.
