The object below is to be cast from aluminum (a cube with a hollow conical volume). If you have problems reading the drawing, the cube side is 100 mm, the cone height is 60 mm and the cone base radius is 30mm. Aluminum data: Density = 2.7 g/cm3, Melting Temperature = 660 °C, Cs = Cl = 0.4 J/g.°C, Hf = 200 J/g, Determine:- The volume of the part to be cast (3 points),- The area of the part to be cast (3 points),- Required energy to heat the metal (3 points),- Solidification time function of the mold constant Cm
