A riser in the shape of a cube is to be designed for a sand-casting mould. The dimensions of the
casting (cuboid thalf cylindrical disk) are shown in figure 1. If the total solidification fime of the casting
itself is known to be 6min, determine the dimensions of the riser so that it will take 20% longer for the
riser to solidify.
