Practice identifying and counting faces, edges, and vertices on common 3D shapes.
Read each problem carefully. Count flat faces, straight edges, and vertices, which are corners. Show your work in the space provided.
Counting flat faces, straight edges, and corners
Math - Grade 2-3
- 1
A cube has 6 flat square faces. How many faces does a cube have?
- 2
Count the vertices on a cube. Remember that vertices are corners.
- 3
A rectangular prism is shaped like a cereal box. How many faces does it have?
- 4
How many edges does a rectangular prism have?
- 5
A square pyramid has 1 square face on the bottom and 4 triangle faces on the sides. How many faces does it have in all?
- 6
How many vertices does a square pyramid have?
- 7
A triangular prism has 2 triangle faces and 3 rectangle faces. How many faces does it have?
- 8
A triangular prism has 6 vertices. If 3 vertices are on one triangle end, how many vertices are on the other triangle end?
- 9
A cube and a rectangular prism both have the same number of faces. How many faces do they each have?
- 10
Which shape has more vertices: a cube or a square pyramid?
- 11
Look at a shape with 4 triangle faces and no square or rectangle faces. This shape is a triangular pyramid. How many faces does it have?
- 12
A triangular pyramid has 4 vertices. How many fewer vertices does it have than a cube?
- 13
A solid shape has 6 faces, 12 edges, and 8 vertices. Is it more like a cube or a square pyramid?
- 14
Maya counts 5 faces and 5 vertices on a shape. She thinks the shape is a square pyramid. Is Maya correct?
- 15
Draw or name one 3D shape that has 8 vertices. Then write how many faces it has.
