Consider the triangular prism shaped wire shown in the figure below where the triangular part is an equilateral triangle with sides $c = 8, 4mm$. The current runs along the length of the wire where $l = 4, 5m$ and the wire has cylindrical hole along its length with a cross sectional area of $A = 2, 1mm^2$. If the wire is made out of a material whose resistivity is $5, 7 \times 10^{-6}\Omega m$ determine the resistance of the wire. Express your answer in unit of $\Omega$ using two decimal places.
