the base of a particular solid is the region bounded by the hyperbola 3x^2 - y^2 = 12 between its vertex (2,0) and its corresponding latus rectum. every cross section of the solid perpendicular to the major axis of the hyperbole is an isosceles right angled triangle with hypotenuse in the base of the solid.

i) show that the latus rectum has equation x=4 (done and dusted)
ii) find the volume of the solid
