Mark constructs a cube of pure gold.  The cube is 6 cm on each side.  The density of gold is 19 grams per cubic centimeter.  He buys the gold for $60 per gram.  He sells it for 1.5 times its gold value.  What was the profit?
How many cubic centimeters are in the cube? ** The cube is 6*6*6=<<6*6*6=216>>216 cubic cm
How many grams does the cube have? ** So it has a mass of 216*19=<<216*19=4104>>4104 grams
How much did Mark spend on the gold? ** So it uses 60*4104=$<<60*4104=246240>>246240
How much does Mark sell the gold for? ** That means he sells it for 246240*1.5=$<<246240*1.5=369360>>369360
How much is Mark's profit? ** So he has a profit of 369360-246240=$<<369360-246240=123120>>123,120
