Example Question #3 : Composing Three Dimensional Shapes

Using the clues below identify the three-dimensional shape.

  • I have 6 flat surfaces.
  • Each flat surface is a square.
  • I have no curved surfaces.

What am I?

Possible Answers:

A sphere

A cone

A cube

A cylinder

Correct answer:

A cube

Explanation:

The three-dimensional figure being described in the riddle is a cube. A cube, like a cardboard box or a die from a board game, has six sides, each side is flat, each side is a square, and there are no curved sides. The other answer choices include curved sides and do not have six flat surfaces.

Example Question #4 : Composing Three Dimensional Shapes

Andy takes two cubes and stacks them on top of each other. What three-dimensional shape did he create?

Screen shot 2020 09 01 at 9.57.26 am

Possible Answers:

Cylinder

Pyramid

Cube

Rectangular Prism

Correct answer:

Rectangular Prism

Explanation:

Andy created a rectangular prism by stacking two cubes on top of each other. A rectangular prism has six flat surfaces, six sides, and four identical faces that are larger than a pair of smaller faces. Each flat surface on a rectangular prism is a square or rectangular shape.
