A specialized type of sand consists of 40% mineral X by volume and 60% mineral Y by volume. If mineral X weighs 4 grams per cubic centimeter and mineral Y weighs 3 grams per cubic centimeter, how many grams does a cubic meter of specialized sand combination weigh? (1 meter = 100 centimeters)  Choose the correct choice.
A) 5,500,000
B) 2,400,000
C) 55,000
D) 28,000
E) 280
Let the volume be 1 m^3 = 1m * 1m * 1m = 100cm * 100cm * 100cm = 1,000,000 cm^3   2,400,000y volume   40% is X = 400,000 cm^3   60% is Y = 600,000 cm^3   2,400,000y weight,   In 1 cm^3, X is 4 gms   In 400,000 cm^3 , X = 4 * 400,000 = 1,600,000 grams   In 1 cm^3, Y is 3 gms   In 600,000 cm^3, Y = 3 * 600,000 = 1,800,000 gms   Total gms in 1 m^3 = 1,600,000 + 1,800,000 = 2,400,000   ANSWER:2,400,000
