The pyramid's formula for Volume is identical to the formula for Volume of a prism, except for having a factor 1/3.
Base Area and height being the same for a pyramid and a prism, the volume of the pyramid is always one third that of the prism.
A similiar fact pertains to Cone vs Cylinder...these 3 dimensional volumes have a ratio of 1/3 to one another.
In two dimensions, there's a ratio of 1/2 between areas of triangles and rectangles having the same base & height.
200 feet is the hypotenuse and the height is the opposite side
sine (34) = height / 200
height = 200 * sine (34)
height = 200 * 0.55919
height = 111.838
Answer: 105
