### Example Question #1 : Composing Three Dimensional Shapes

The sides of a rectangular prism are made up of __________.

Circles

Triangles

Trapezoids

Rectangles

Rectangles

Explanation:

The sides of a rectangular prism are made up of rectangles.

### Example Question #3 : Composing Three Dimensional Shapes

The base, or bottom, of a cylinder is made of up what shape?

Rectangle

Circle

Square

Triangle

Circle

Explanation:

The base, or bottom, of a cylinder is made up of a circle.

### Example Question #51 : Reason With Shapes And Their Attributes

The sides of a cube are made up of ____________.

Rectangles and squares

Squares

Triangles

Rectangles

Squares

Explanation:

A cube is a 3-dimensional shape with 6 sides. Each side of a cube is a square. Thus, the sides of a cube are made up of squares.

### Example Question #52 : Reason With Shapes And Their Attributes

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?

A cone

A cube

A cylinder

A sphere

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 #52 : Reason With Shapes And Their Attributes

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

Cube

Cylinder

Rectangular Prism

Pyramid

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.

### Example Question #2 : Composing Three Dimensional Shapes

Using the clues below identify the three-dimensional shape.

• I have five flat surfaces.
• Four of my surfaces are triangles.
• I have no curved surfaces.

What am I?

Explanation:

The three-dimensional figure that is being described in the riddle is a pyramid. A pyramid has four surfaces that are triangles, no curves surfaces, and a total of five flat surfaces. The base of the pyramid in the example is a square. The other figures have curved surfaces and do not match the clues.

### Example Question #1531 : Common Core Math: Grade 1

Using the clues below identify the three-dimensional shape.

• I have zero flat surfaces.
• I have zero faces.
• I have no edges.

What am I?
