Problem 6 (10 points)

A flat plate is to be cast in an open mold whose bottom has a rectangular shape of 10.5 cm by 15.5

cm. The mold is 7.0 cm deep. A total of 750 cm³ of molten aluminum is poured into the mold.

Solidification shrinkage is known to be 6.25%, which is a volumetric contraction, not a linear

contraction. Table 7.1 lists the linear shrinkage due to thermal contraction after solidification. If the

availability of molten metal in the mold allows the cast plate to maintain its rectangular dimension

until solidification is completed, determine the final dimensions (length, width and height) of the plate.
