A graph titled Position versus time for 3 runners with horizontal axis time (seconds) and vertical axis position (meters). A blue line labeled A has the greatest upward slope followed by an orange line labeled B. A green line labeled C runs from a positive distance above 0 meters at 0 seconds straight across at the same distance for all times. Lines A and B intersect 0 seconds 0 minutes. Use the drop-down menus to complete each sentence.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
