A flat plate is to be cast in an open mold whose bottom has a square shape of 12.5 cm by 12.5 cm. The mold is 7.0 cm deep. A total of 350 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 square shape of the cast plate to maintain its square dimension until solidification is completed, determine the final dimensions (width and height) of the plate.

Question
A flat plate is to be cast in an open mold whose bottom has a square shape of 12.5 cm by 12.5 cm. The
mold is 7.0 cm deep. A total of 350 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 square shape of the cast plate to maintain its square dimension until
solidification is completed, determine the final dimensions (width and height) of the plate.
