A) 0.80
B) 1.25
C) 8.00
D) 12.50
E) 80.00


800 kg - 1 cubic meter;
800,000 g - 1 cubic meter;
800,000 g - 1,000,000 cubic centimeters;
1 g - 1,000,000/800,000 = 10/8 = 1.25 cubic centimeters.

Answer: B.

Thanks, Bunuel. Sorry about posting in the wrong forum.
I am confused, because isn't 1,000,000 cubic centimeters / 800,000 g the density of the substance. That is 1.25 cubic cubic centimeters per gram of the substance. The question asked for volume, not density.

Density is mass divided by volume. So density of the given substance will be mass/volume=800kg/1m^3=800 kg/m^3 or 1g/1.25cm^3=0.8 g/cm^3.

Next, ask yourself if 800,000 g is equivalent to 1,000,000 cubic centimeters then 1 g is equivalent to how many cubic centimeters? --> 1 g - 1,000,000/800,000 = 10/8 = 1.25 cubic centimeters.

Hope it's clear.
