Surface Area and Volume of Pyramids

The video tutorial explains how to calculate the surface area of pyramids with different bases. It starts with a square-based pyramid, detailing the process of finding the area of the base and the triangular sides. The tutorial then provides a second example with a similar square base, followed by a more complex example involving a triangular base. Each step is broken down to ensure understanding of the geometric principles involved.

What is the first step in finding the surface area of a pyramid with a square base?

• Measure the height of the pyramid

• Count the number of sides

• Calculate the volume of the pyramid

• Find the area of the base

How do you calculate the area of a square base with side length 5?
