<h3>Surface area of a pyramid</h3>
This the sum of all the area of the surfaces. The given figures is made of 3 rectangles and 2 triangles
<u>Determine the surface area</u>
TSA = (25*25) + (2 * 5*301/12) + (5*2.08333)
TSa = 625 + 258.33333 + 10.41665
TSA = 893.74995
If a quart of stain covers 100 square feet, the total nuber to buy is given as:
