Kellogg Eye Center Vitreous Degeneration 1 ! Vitreous Degeneration This material will help you understand vitreous degeneration and how it is treated. What is vitreous degeneration? Vitreous is the gel-like substance that fills the inside of the eye behind the lens (see image on the right). Before you were born, it helped maintain the shape of the eye and nourish the eye as it developed.
The formula used to calculate surface area for the classic square pyramid is: SA = [2 * b * h] + b^2. 1  SA and l represent the same values as before. 2  The abbreviation b represents the base length of the pyramid. 3  Note that [2 * b * h] is used to calculate the lateral area of the square pyramid.
The area formula for a triangle is its base times its height divided by two. In the case of one of the triangles above it would be s x l Ã· 2. However, there are four triangles. This would make the total lateral surface area equal to four times the area of one triangle, or 4 x s x l Ã· 2.he total surface area of the pyramid is equal to the area of the base plus its lateral surface area or s 2 + 2sl. So, given the base length of the pyramid, s, and its slant height, l, the total surface area is not a difficult computation.
