# Cuboid Surface Area Calculator

Cuboid Surface Area Calculator – a powerful tool designed to make calculating the surface area of a cuboid quick and straightforward. A cuboid, also known as a rectangular prism, is a three-dimensional shape with six rectangular faces. Understanding its surface area is crucial in various fields such as mathematics, engineering, and architecture. This tool aims to simplify the process of calculating the cuboid's surface area, providing a valuable resource for students and enthusiasts.

### What is the Cuboid Surface Area ?

The surface area of a cuboid refers to the total area of all its six faces. It includes the area of the top, bottom, front, back, left, and right faces of the cuboid.

### What is the formula for calculating Cuboid Surface Area ?

The formula for cuboid surface area is:

`SA = 2(length*width) + 2(width*height) + 2(length*height)`

SA stands for Surface Area.

l represents the length of the cuboid.

w represents the width of the cuboid.

h represents the height of the cuboid.

### How is the Cuboid Surface Area Calculated ?

The surface area (SA) of a cuboid can be calculated using the above mentioned formula

### Why is the Surface Area of a Cuboid Important to Understand ?

Understanding the surface area of a cuboid is essential for applications such as packaging design, architectural planning, and understanding geometric principles in mathematics and engineering.

### Examples

Example 1:

Given: Length (l) = 5 units Width (w) = 3 units Height (h) = 4 units

Calculation:

Using the formula

SA = 2(length*width) + 2(width*height) + 2(length*height)

SA = 2(5*3) + 2(3*4) + 2(5*4)

SA = 30 + 24 + 40

SA = 94 square units

Example 2:

Given: Length (l) = 8 units Width (w) = 6 units Height (h) = 10 units

Calculation:

Using the formula

SA = 2(length*width) + 2(width*height) + 2(length*height)

SA = 2(8*6) + 2(6*10) + 2(8*10)

SA = 32 + 120 + 160

SA = 376 square units
