Shape Identification and Properties

Look at the purple 3D shape. What is the name of this shape?

• cylinder

• cube

• cuboid

• cone

Which shape is the odd one out, and why? Choose the shape and the reason.

• Cylinder because it has curved edges

• Pyramid because it has triangular faces

• Cube because it has only flat faces

• Cylinder because it has curved surface

How many vertices does a cube have? Write the number.

Look at the cube and the rectangular prism. Do these two shapes have the same number of vertices?

• Yes, they both have two vertices

• No, the cube has fewer vertices

• Yes, they have the same vertices

• No, the prism has fewer vertices

How many surfaces does a sphere have?

• Zero surfaces at all

• One continuous surface

• Two separate surfaces

• Three flat surfaces

A cone is shown. How many surfaces does a cone have?

• One curved surface only

• Two surfaces total

• Three surfaces total

• Four surfaces total

Look at the picture. What is the name of this 3D shape with a triangular base and a point at the top?

• Triangular prism

• Rectangular prism

• Triangular-based pyramid

• Square-based pyramid

How many edges does a triangular-based pyramid have?

• nine edges total

• eight edges total

• seven edges total

• six edges total

A sphere is smooth all around. How many edges does a sphere have?

• one edge

• two edges

• three edges

• zero edges

Look at the cylinder and cone. Which shape has more surfaces?

• The cylinder has more surfaces

• The cone has more surfaces

• They have the same number
