**Introduction**

Geometry, the study of shapes and their properties, plays a crucial role in various fields, from architecture and engineering to art and design. One fundamental geometric shape often encountered in these disciplines is the cuboid, a three-dimensional figure with six rectangular faces. Calculating the surface area of a cuboid is a common task in these fields, and a Surface Area of a Cuboid Calculator simplifies this process, making it accessible to everyone.

**Formula:**

Before we delve into the practical use of the calculator, it’s essential to understand the formula for calculating the surface area of a cuboid. A cuboid has six faces, each of which is a rectangle. The formula for the surface area (SA) of a cuboid is given by:

SA = 2(lw + lh + wh)

Where:

- SA represents the surface area.
- l, w, and h are the lengths of the three pairs of opposite sides of the cuboid.

**How to Use?**

Using the Surface Area of a Cuboid Calculator is simple and convenient:

**Input Values:**Gather the measurements of the cuboid’s length (l), width (w), and height (h).**Enter Values:**Input these measurements into the calculator.**Calculate:**Click on the “Calculate” button to receive the surface area of the cuboid instantly.**Result:**The calculator will display the surface area of the cuboid in square units (e.g., square inches or square meters).**Apply the Result:**Use the calculated surface area in your architectural plans, engineering projects, or any other relevant applications.

**Example:**

Let’s say you have a cuboid with the following measurements:

- Length (l) = 8 cm
- Width (w) = 5 cm
- Height (h) = 3 cm

Using the formula:

SA = 2(lw + lh + wh) SA = 2(8 cm * 5 cm + 8 cm * 3 cm + 5 cm * 3 cm) SA = 2(40 cm² + 24 cm² + 15 cm²) SA = 2(79 cm²) SA = 158 cm²

The surface area of this cuboid is 158 square centimeters.
