Introduction

When it comes to geometry, one of the most fundamental shapes is the cube. A cube is a three-dimensional solid object with six square faces, each of which is a rectangle with four equal sides. In this article, we will delve into the concept of the volume of a cube and provide a step-by-step guide on how to calculate it.

What is the Volume of a Cube?

The volume of a cube is the amount of space inside the cube. It is a measure of the cube's capacity to hold objects or substances. The volume of a cube is typically denoted by the symbol V and is measured in cubic units, such as cubic centimeters (cm³) or cubic meters (m³).

Formula for Calculating the Volume of a Cube

The formula for calculating the volume of a cube is:

V = s³

Where V is the volume of the cube and s is the length of one side of the cube.

How to Calculate the Volume of a Cube

To calculate the volume of a cube, you need to know the length of one side of the cube. Once you have this information, you can simply cube the length of the side to get the volume.

For example, let's say we have a cube with a side length of 7 cm. To calculate the volume of this cube, we would follow these steps:

Identify the length of one side of the cube, which is 7 cm.
Cube the length of the side by multiplying it by itself three times: 7 cm × 7 cm × 7 cm.
Calculate the result of the multiplication: 7 cm × 7 cm = 49 cm², and then 49 cm² × 7 cm = 343 cm³.

Therefore, the volume of the cube is 343 cm³.
