3D Shapes Faces, Vertices And Edges Quiz

1)

Which shape is a cube?

A

C

D

The shape D is a cube because it has six equal square faces. A cube is a three-dimensional shape with equal length, width, and height, and all its faces are congruent squares. Therefore, shape D fits this description and is a cube.

Explanation

The shape D is a cube because it has six equal square faces. A cube is a three-dimensional shape with equal length, width, and height, and all its faces are congruent squares. Therefore, shape D fits this description and is a cube.

2) Which two solids below have the same number of faces?

Solids B and C

Solids A and B

Solids A and D

Shape A is a rectangular prism, which has 6 faces.

Shape B is a cylinder, which has 3 faces.

Shape C is a sphere, which has 1 continuous curved surface and no distinct faces.

Shape D is a cube, which also has 6 faces.

Shapes A and D both have 6 faces. Therefore, these two solids have the same number of faces.

Explanation

Shape A is a rectangular prism, which has 6 faces.

Shape B is a cylinder, which has 3 faces.

Shape C is a sphere, which has 1 continuous curved surface and no distinct faces.

Shape D is a cube, which also has 6 faces.

Shapes A and D both have 6 faces. Therefore, these two solids have the same number of faces.

3) Which statement below is true?

This solid figure had 6 corners (vertices).

This solid figure is called a pyramid.

This solid figure has 8 faces.

The solid figure shown is a triangular prism, which has 6 vertices, 9 edges, and 5 faces (2 triangular and 3 rectangular). It is not a pyramid, as a pyramid has a single base and converges to a single point (apex). A triangular prism has two parallel triangular bases connected by rectangular faces. Each corner where edges meet is called a vertex, and there are 6 vertices in total in a triangular prism.

5) Which shape has three faces?

A

B

C

D

A cylinder has two circular faces (one on the top and one on the bottom) and one curved rectangular face that wraps around the sides. This totals three faces: two flat circular faces and one curved face.

Explanation

A cylinder has two circular faces (one on the top and one on the bottom) and one curved rectangular face that wraps around the sides. This totals three faces: two flat circular faces and one curved face.

The shape in the image is a triangular prism.

A triangular prism has 5 faces:

2 triangular faces (the two ends)

3 rectangular faces (connecting the sides of the triangles)

So, the shape shown has 5 faces.
