how do you find the surface area of a square based pyramid with only the height of the pyramid itself and the width (of the base)?
a square based pyramid has 5 sides, one square side and 4 isosceles triangles
h=height, w=width (width of the base)
the area of the base is w^2
the area of a triangle is 1/2*base*height
the area of one of the triangular sides is 1/2*w*h
surface area A=w^2+4*((1/2)*w*h)
A=w^2+2*w*h
