Surface Area of a Rectangular Pyramid. The surface area of a regular square pyramid is the sum of area of the base and area of four isosceles triangles.

Water and Warm Liquids. Water and warm liquids can soften stool. Liquids can help ease pressure in your intestines caused by hard, dry stools. In addition, warm liquids like coffee, hot lemon water and tea are considered natural laxatives that push waste and toxins through your intestines.
Stool softeners help by adding moisture to the stool, allowing for easier passage through the bowel. Stool softeners come in liquid or pill form, and usually contain docusate. They do not actually increase or stimulate bowel movements.
