## What is Rectangular Prism?

A rectangular prism, also known as a rectangular cuboid, is a three-dimensional geometric shape characterized by six rectangular faces, twelve edges, and eight vertices (corners). It is a specific type of prism where all the faces are rectangular in shape, and the opposite faces are congruent and parallel.

## All Formulae Related to Rectangular Prism

1. Volume of a Rectangular Prism (V):
• The volume of a rectangular prism is the measure of the space it occupies.
• Formula: V = length × width × height
2. Surface Area of a Rectangular Prism (SA):
• The surface area of a rectangular prism is the total area of all its six faces.
• Formula: SA = 2lw + 2lh + 2wh
• Where l = length, w = width, and h = height
3. Diagonal Length of a Rectangular Prism (d):
• The diagonal length of a rectangular prism is the longest distance between two opposite corners.
• Formula: d = √(l² + w² + h²)
• Where l = length, w = width, and h = height

## Practical Uses of Rectangular Prism

Rectangular prisms have practical applications in various fields due to their common and versatile shape. Here are some practical uses of rectangular prisms in everyday life and various industries:

1. Packaging and Shipping:
• Many products are packaged and shipped in rectangular prism-shaped containers or boxes due to their efficiency in utilizing space.
2. Building and Construction:
• Rectangular prisms are used as building blocks for constructing walls, columns, and various structural components in architecture.
3. Furniture Design:
• Furniture pieces like cabinets, drawers, and bookshelves are designed using rectangular prisms to maximize storage space.
4. Storage Containers:
• Plastic bins, storage boxes, and crates are rectangular prisms, making them suitable for organizing and storing items.
5. Electrical Components:
• Many electrical and electronic devices, such as batteries and circuit boards, are housed in rectangular prism-shaped enclosures.
