Calculating Volume: Different Shapes and Formulas

Calculating the volume of an object depends on its shape. Here are some common shapes and their corresponding formulas:

• Cube: Volume = side × side × side = side³
• Cuboid (Rectangular Prism): Volume = length × width × height
• Sphere: Volume = (4/3)πr³ (where r is the radius)
• Cylinder: Volume = πr²h (where r is the radius and h is the height)
• Cone: Volume = (1/3)πr²h (where r is the radius and h is the height)
• Pyramid: Volume = (1/3)Bh (where B is the area of the base and h is the height)

For irregular shapes, more advanced techniques like water displacement or 3D scanning might be needed to determine the volume.

Understanding Density and its Relationship to Volume

Density is closely related to volume. Density is defined as mass per unit volume (density = mass/volume). Knowing the volume and mass of an object allows us to calculate its density, a key property used in material identification and various scientific applications. For instance, gold has a much higher density than wood, meaning a given volume of gold will have a significantly greater mass than the same volume of wood.
