The height of the pyramid is [tex]16ft.[/tex]
What does it mean by right pyramid?
The centroid of the base sits just above the right pyramid. Oblique pyramids are non-right pyramids. A right pyramid is typically assumed to be a regular pyramid because it has a regular polygon base.
To find the height of the pyramid:
l=the slant height of the right pyramid.
b=the length side of the square base of the right pyramid.
h=the height of the right pyramid.
Pythagorean Theorem: [tex]l^{2} =h^{2} +(\frac{b}{2} )^{2}[/tex]
Solve:h
[tex]h^{2} =l^{2} +(\frac{b}{2} )^{2}[/tex]
[tex]h^{2} =20^{2} -12^{2}[/tex]
[tex]h^{2} =256[/tex]
[tex]h=16ft[/tex]
Therefore, The height of the pyramid is [tex]16ft.[/tex]
