3h^2=512        [ /3

h^2 = 160.666...

h = √160.666...

 

h₁ = 13.0639452949

h₂ = - 13.0639452949

\(\color{red}3h^2=512\)

\(\color{orange}h^2=\frac{512}{3}\)

\(\color{lime}h^2+0h-\frac{512}{3}=0\)

Using quad. formula

\(\color{blue}h_1=13.063945294843617\)

\(\color{purple}h_2=-13.063945294843617\)
