## Sketch

### Volume of a cuboid

**Formula**: a * b * h = V

**Example calculation:** 10cm * 5cm * 6cm = ^{300cm3}

### Shell of a cuboid

**Formula**(a b) * 2 = M

Shell = (circumference of the base) * 2

Example calculation**:** (12cm 7cm) * 2 = ^{38cm2}

### Surface area of a cuboid

**Formula**: 2 * (a * b a * c b * c) = O

Example calculation**:** 2 * ((10cm * 5cm) (10cm * 4cm) (5cm * 4cm)) = ^{220cm2}

## Properties

A cuboid is a geometric figure and consists of six rectangles, two of which are parallel to each other.

The solid has

- six rectangles as a surface, which are at right angles to each other.
- eight right-angled corners and eight vertices.
- twelve edges (four of which have the same length (a)).

Here are some examples of how to calculate the surface area, the envelope or the volume (volume) of a cuboid:

The formula for the volume of a cuboid is **V = a * b * h**. To calculate the volume, you need the length a, the width b and the height h.

The lateral surface area is the sum of the four side surfaces. The formula for the lateral surface is **M = (a** b **) * 2**. The lateral surface is the surface of the body without the base surface and the top surface.

The formula for the surface area is **O = 2 * (a * b a * c b * c)** or, put more simply, **O = 2ab 2ac 2bc**. The surface area is therefore the lateral surface area plus the base area and the top area.
