Volume Calculator: Calculate Volume Online Easily

Introduction

A Volume Calculator is an easy-to-use online tool that helps you find the volume of different 3D shapes within seconds. Volume is the amount of space a solid object occupies, and it is usually measured in cubic units (cm³, m³, ft³, etc.). Instead of memorizing multiple formulas or doing manual calculations, you can simply enter the required dimensions, and the calculator will instantly give you the result.

This tool is useful for students, architects, engineers, contractors, and even homeowners who want to estimate storage capacity, liquid filling, or material usage. With a Volume Calculator online, you can calculate volumes of cubes, spheres, cylinders, cones, pyramids, and more without errors.

Formula / Working

The calculator works by applying standard geometric formulas depending on the shape selected. Here are the most common ones:

Cube: V=a3V = a^3V=a3 where a = side length.
Rectangular Box (Cuboid): V=l×w×hV = l \times w \times hV=l×w×h where l = length, w = width, h = height.
Sphere: V=43πr3V = \tfrac{4}{3}\pi r^3V=34πr3 where r = radius.
Cylinder: V=πr2hV = \pi r^2 hV=πr2h where r = radius, h = height.
Cone: V=13πr2hV = \tfrac{1}{3}\pi r^2 hV=31πr2h
Pyramid: V=13×Base Area×hV = \tfrac{1}{3} \times \text{Base Area} \times hV=31×Base Area×h

The calculator automatically applies the correct formula based on your input.

Step-by-Step Usage

Using the Volume Calculator online is very simple:

Open the tool in your browser.
Choose the shape you want to calculate (cube, sphere, cone, etc.).
Enter the required dimensions (radius, height, length, etc.).
Click the Calculate button.
Instantly view the volume result in cubic units.

Examples

Example 1: Cube

A cube has side length = 5 cm. V=a3=53=125 cm3V = a^3 = 5^3 = 125 \, cm^3V=a3=53=125cm3

✅ The calculator will show 125 cm³.

Example 2: Cylinder

Radius = 4 cm, Height = 10 cm V=πr2h=3.14×16×10=502.4 cm3V = \pi r^2 h = 3.14 \times 16 \times 10 = 502.4 \, cm^3V=πr2h=3.14×16×10=502.4cm3

✅ The calculator will show 502.4 cm³.

Example 3: Sphere

Radius = 6 m V=43πr3=43×3.14×216=904.32 m3V = \tfrac{4}{3}\pi r^3 = \tfrac{4}{3} \times 3.14 \times 216 = 904.32 \, m^3V=34πr3=34×3.14×216=904.32m3

✅ The calculator will show 904.32 m³.
