  What id Pyramid? •Pyramidsare three-dimensional geometric shapes where the base is a polygon, and all other sides are triangles that meet at the apex or vertex
• 7.
  •The height ofthe pyramid is the perpendicular height, which is the distance from the apex or vertex to the base of the pyramid. •The slant height is the distance measured along a lateral face from the apex to the base edge. It is the height of the triangle, which is the lateral face of the pyramid.

  RECTANGULAR PYRAMID •A RectangularPyramid is a three- dimensional geometric shape that has a rectangular base and four triangular faces (lateral faces) that are joined at the top by a vertex or apex.

  Example: Find the volumeof a rectangular pyramid whose base is 6 x 7 inches and a height of 10 inches.
• 13.
  Example: Find the volumeof a rectangular pyramid if its base length is 10 meters, its base width is 6 meters, and its height is 14 meters.

  Example: Suppose that thegovernment of the City of Manila is planning to build a pyramidal water reservoir. The base area of the reservoir has to be 12,545 square feet (ft2). Given that its height is 51 feet (ft), find the volume of the reservoir.
