The formula is V = [1/2 x 5 x side x apothem] x height of the prism. You can use the first part of the formula to find the area of the pentagonal base face.

We use quadratic formula for that one
remember that √-1=i

so

for
ax^2+bx+c=0
$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$
so
given
5x^2-6x+2=0
a=5
b=-6
c=2

$x=\frac{-(-6)+/-\sqrt{(-6)^2-4(5)(2)}}{2(5)}$
$x=\frac{6+/-\sqrt{36-40}}{10}$
$x=\frac{6+/-\sqrt{-4}}{10}$
$x=\frac{6+/-2i}{10}$

$x=\frac{3}{5}+\frac{i}{5}, \frac{3}{5}-\frac{i}{5}$
