Use the Pythagorean theorem:
a^2 + b^2 = c^2
a = sqrt (c^2 - b^2)
Where:
a=the height (pyramid height from base to peak)
b=the base length
c = the hypotenuse (slant) length
LA=1/2ps
Surface area of any pyramid is 1/2Pl + B; where P=perimeter of the base, l=slant height and B= Area of the base.
By using trigonometry or Pythagoras' theorem

Why do you need to FIND the slant height if you have the [lateral height and] slant height?

if you know the height and the apothem, use pythagorean theorem to solve for it.
Why do you need to FIND the slant height if you have the [lateral height and] slant height?
Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.
You have to find out the area of the base which you find out with perpendicular height times base then time that by the perpendicular height of the pyramid and divide it by 3
You need some information about the height of the pyramid and the formula will depend on whether you have the vertical height or the slant height or the length of a lateral edge.
use formula bh/2. Substitute base with 15 and height with 13.75 and divide the product by two. That is the slant height.
