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. But for rectangular pyramid, with rectangular base, we can not use the standard formula of surface area because there is more than one slant height ($s_1$ and $s_2$).
Step 1. Drink plenty of water with your meals and between meals. Water helps soften your stool. If you do not drink enough fluids, your body will pull water from the colon, hardening the stools. Also avoid caffeinated beverages, which cause your body to lose water.
Stool softeners (such as Colace and Docusate Calcium) soften the stool, making it easier to pass. Stool softeners can be most effective if you drink plenty of water throughout the day. Osmotic laxatives, such as Fleet Phospho-Soda, Milk of Magnesia, or Miralax, and nonabsorbable sugars (such as lactulose or sorbitol), hold fluids in the intestine.
