Exploring Unit Eleven Concepts

This video tutorial covers the concept of volume in geometry, focusing on prisms, pyramids, cylinders, and cones. It explains how to calculate the volume of these shapes using the area of the base and height, and introduces the concept of slant height in pyramids. The tutorial includes practical examples and calculations, emphasizing the importance of exact values in mathematical computations.

What is the formula for the volume of a prism?

• 1/3 area of the base times height

• Area of the base times slant height

• Area of the base times height

• 1/2 area of the base times height
