Consolidating 3D shape learning

Maths

A flat or curved surface of the 3-D shape.

The corners where the edges of the shape meet.

The part of the shape where 2 surfaces meet.

What is the definition of the 'face' of a 3-D shape?

False- the number of vertices is always less than the number of faces.

False- the number of vertices is always the same as the number of faces.

True- but it is not possible to have less vertices than faces.

True- it is possible to have more or less vertices than the number of faces.

'It is possible for a shape to have more vertices than faces.' Is this statement true or false?

Which of the following 3-D shapes has the most vertices?

Which of the following 3-D shapes has both curved and flat faces?

Which of the following is another term for a triangular-based pyramid?

How many edges does a triangular prism have?

False- cubes have 10 edges and cuboids have 12 edges.

False- it depends on the size of the cube and cuboid.

'Cubes and cuboids have the same number of edges.' Is this statement true or false?

A triangular prism has 2 faces which are triangles and 3 faces which are rectangles whereas a triangular-based pyramid has 4 triangular faces.

A triangular prism has fewer vertices than a triangular-based pyramid.

A triangular prism is always bigger than a triangular-based pyramid.

A triangular-based pyramid is always bigger than a triangular prism.

Identify one of the differences between a triangular prism and a triangular-based pyramid.

'I have 2 flat surfaces and 1 curved surface. I also have 2 curved edges.' What am I?

'I have 8 faces and 12 vertices. I also have 18 edges.' What am I?
