Volume Calculations for Prisms

This video tutorial covers the concept of volume, focusing on calculating the volume of different prisms and cylinders. It begins with a simple explanation of volume using a rectangular prism, emphasizing that the order of dimensions does not affect the result. The tutorial then explores the volume of other prisms, such as triangular and trapezoidal prisms, by finding the area of the base and multiplying by the height. Advanced calculations for complex prism shapes are discussed, followed by volume calculations for cylinders and special cases. The tutorial concludes with a practical example involving a pool and a garden hose.

What is the formula for calculating the volume of a rectangular prism?

• Length + Width + Height

• 2 × (Length + Width + Height)
