Calculating Volume and Surface Area of Pyramids

This video tutorial explains how to find the volume and surface area of pyramids. It begins with an introduction to the formulas used for these calculations. The volume of a pyramid is calculated using the formula 1/3 times the area of the base times the height. An example is provided where the base is a rectangle, and the volume is calculated step-by-step. The tutorial then moves on to calculating the surface area of a pyramid, which involves finding the area of the base and the triangular faces. The process is demonstrated with examples, emphasizing the importance of using correct units for volume and area.

What is the formula used to calculate the volume of a pyramid?

• 1/3 * base area * height

• 1/2 * base area * height

• base area * height

• 2 * base area * height
