How many faces does a 2D rectangle have?

One.

How many faces does a rectangle have in geometry?

A rectangle is a 2D object with four sides or edges, but does not have any faces. Only 3D objects have faces. A rectangular pyramid has six faces.

How many faces does a triangle prism have?

There are 2 triangle base faces, and 3 rectangle faces. 5 total faces.

How many faces does a 3D rectangle have?

i believe it is 6 there's your answer:)

How many flat surfaces in a rectangle prism?

There are six faces in a rectangular prism6 faces

Rectangular prisms

A rectangular prism is a three-dimensional object with rectangles as all of its faces. If all the faces of the prism are squares, then the rectangular prism can also be called a cube.

The net of a polyhedron is like an unfolded cardboard construction of that polyhedron. One example is the rectangular-prism cereal packet and its net shown here.

A rectangular prism has 6 faces, 8 vertices (or corners) and 12 edges. To build a rectangular prism with construction materials, we would need 6 rectangles that join at the edges to make a closed three-dimensional shape or 12 edge pieces and 8 corner pieces to make a frame of a rectangular prism.
A cube or rectangular prism can also be called a hexahedron because it has six faces. Hexa means six.

Have you ever been given a gift box or party hat? 🎁

They're all 3D shapes.

3D shapes are made of vertices, edges, and faces!

Vertices are the pointy bits or the corners where edges meet.

Edges are the lines around a shape.

Faces are the flat sides that you touch when you hold a shape.

Let's look at how many vertices, edges, and faces different 3D shapes have. 👇

Cubes

Cubes have 6 square faces. 

If you glue 6 square faces together, they becomes a cube with 8 vertices and 12 edges.

Rectangular Prisms

Here's a rectangular shaped gift box:

It's made up of 6 rectangular faces. 

When you join the sides together, it becomes a rectangular prism with 8 vertices and 12 edges.

Tip: All cubes are rectangular prisms, but not all rectangular prisms are cubes. 

It's kind of like how all squares are rectangles, but not all rectangles are squares.

Triangular Prisms

Here's a triangular gift box:

It's made up of 5 faces (2 are triangles, 3 are rectangles). 

Triangular prisms have 6 vertices and 9 edges! Can you count them?

Pyramids

Pyramids are made up of 5 faces (4 are triangles, 1 is a square). 

When you join the faces together, it becomes a square-based pyramid with 5 vertices and 8 edges!

Cylinder

Cylinders have 2 circular faces and 1 curved surface. 

Curved surfaces don't count as faces. Faces are flat. 

When you wrap the surface around the circles, it becomes a cylinder with 2 edges and 0 vertices. 

There are no sharp, pointy bits in a cylinder!

Cones

Cones like this party hat are made up of 1 surface and 1 circular face.

Cones have 1 vertex and 1 edge.

Spheres

Spheres have 0 faces, 0 edges and 0 vertices. 

How would you gift wrap a sphere? It's tough without crumpling paper.

Great job! Now, you know all about vertices, faces, and edges!

Now, complete the practice. It helps you learn more and remember for longer.
