The video tutorial covers the calculation of volumes for pyramids and cones. It begins with an introduction to the concepts of height and volume, followed by the formula for finding the volume of a pyramid: V = 1/3 * B * H, where B is the area of the base and H is the height. The tutorial includes examples and exercises for students to practice calculating the volume of pyramids with square bases. It then transitions to cones, explaining that the volume formula is similar, using the area of a circular base. The video provides examples and exercises for calculating cone volumes, emphasizing the use of the circle area formula.

What is the formula for calculating the volume of a pyramid?

• V = 1/2 * B * H

• V = π * r^2 * H

• V = B * H

• V = 1/3 * B * H

How is the height of a pyramid or cone measured?

• From the base to the vertex along the slant

• From the vertex to the base along a line perpendicular to the base

• From the center of the base to the vertex

• From one edge of the base to the opposite edge
