Work of a triangular cycle

An ideal gas goes through the triangular cycle $A\to C\to B\to A$ with $A$ ($1.00\mathrm{L}$; $1.00\cdot 10^5\mathrm{Pa}$), $C$ ($1.00\mathrm{L}$; $3.00\cdot 10^5\mathrm{Pa}$) and $B$ ($3.00\mathrm{L}$; $1.00\cdot 10^5\mathrm{Pa}$), where each side is traversed quasi-statically along a segment of the $(V,p)$ plane. Compute the total work and the total heat exchanged in the cycle.
