## âœ…What is a Cuboid?

**A cuboid** is a three-dimensional shape that has **six rectangular faces.** A cuboid's
length, width, and height are of different measurements. The corners of these faces
form right angles. Cuboids have **eight vertices and twelve edges.**

## âœ…How to calculate the Volume of a cuboid

To calculate the **Volume of a cuboid**, we use the following formula:

**ðŸ‘‰Volume=( l Ã— b Ã— â„Ž) cubic units**

So if we have the following problem:

**ðŸ‘‰Find the volume of a cuboid whose length is 12 cm, width is 9 cm, and height is 10 cm.**

Using the above formula, we can then say:

**ðŸ‘‰Volume=(12Ã—9Ã—10) cm3volume=(12Ã—9Ã—10) cm3**
**ðŸ‘‰Volume=1080 cm3volume=1080 cm3**

## âœ…How to calculate the surface area of a cuboid

To calculate the **Area of a cuboid**, we use the following formula:

**ðŸ‘‰Area=2( lw + wh + lh) sq units**

So if we need to find the total surface area of a cuboid whose length is `8 cm`

, width is `7 cm`

, and height is `6 cm`

, using the above, we begin by substituting the values:

**ðŸ‘‰Area=2((8Ã—7)+(7Ã—6)+(8Ã—6)) cm2**
**ðŸ‘‰Area=2(56+42+48) cm2**
**ðŸ‘‰Area=2((8Ã—7)+(7Ã—6)+(8Ã—6)) cm2**
**ðŸ‘‰Area=292 cm2**
