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.
Volume = (length * width * height) / 3. Its surface area is easier to calculate if it is a right pyramid and has a square base: Surface area = (1/2 * base perimeter * slant height) + base area. If the pyramid is oblique or doesn't have a square base, then the faces have to be calculated individually. Always remember to put the proper units on your calculation - squared for surface area and cubed for volume.
