Spec G17
  • The volume of a pyramid is a third the volume of a prism with the same base and height
  • The volume of a prism is equal to the area of its base times its vertical height
  • The volume of a pyramid with the same base and height will equal a third times the base area times its vertical height
  • To calculate the volume of a pyramid, you need to know its vertical height and the area of its base
  • The formula for the volume of a pyramid is a third times the base area times the vertical height
  • Example: Calculate the volume of a pyramid with a rectangular base
  • Step 1: Determine the shape of the base (rectangle)
  • Step 2: Calculate the area of the base using the formula for a rectangle (length times width)
  • Step 3: Use the formula for the volume of a pyramid to calculate the volume (a third times the base area times the vertical height)
