## What is the net for a rectangular prism?

six rectangles

The net of a rectangular prism consists of six rectangles. Both the bases and the lateral faces of this shape are rectangles. The net of a pentagonal prism consists of two pentagons and five rectangles. The pentagons are the bases of the prism and the rectangles are the lateral faces.

### How many nets does a rectangular prism have?

In this lesson, the focus is on nets for rectangular prisms. There are many possible nets for any given prism. For example, there are 11 different nets for a cube, as shown below.

#### What is the area of the prism net?

To find the surface area of a prism, it can be helpful to sketch the net, find the area of each shape in the net, and then add the areas together. To find the surface area of this triangular prism, find the area of the three rectangles and two triangles in its net and add all the areas together.

**How is surface area calculated?**

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

**What is the difference between a right rectangular prism and a rectangular prism?**

A right rectangular prism has its side faces perpendicular to each of its bases. An oblique rectangular prism is a prism that is NOT a right rectangular prism and its side faces are parallelograms. In general, a rectangular prism without any specifications is a right rectangular prism.

## What are examples of rectangular prisms?

Right rectangular prisms or cuboids are all around us. A few of the examples are books, boxes, buildings, bricks, boards, doors, containers, cabinets, mobiles, and laptops. Non-examples of right rectangular prism: This shape is a prism but its top and base do not have right angles in the shape.

### How do you find the surface area of a rectangular prism with a net?

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.
