Lesson 1: Volume of a Pyramid Volume of Pyramid: V = ⅓Bh, where B = base area and h = height; the volume of a pyramid is ⅓ the volume of a rectangular prism

Lesson 1: Volume of a Pyramid Find the volume. A.A regular hexagonal pyramid with side length 12 ft and height equal to the apothem of the base.

Lesson 1: Volume of a Pyramid B.At the top of the Washington Monument is a small square pyramid called a pyramidion. This pyramid has a height of 55.5’ with a base edge of 34.5’. What is the volume of the pyramidion?

Lesson 2: Using Volume

12.5(a): Do I Get It? Yes or No Find the volume A pyramidion that was discovered in Saqqara, Egypt, in 1992 has a rectangular base 53 cm by 37 cm. It is 46 cm high. What is the volume of the pyramidion?
