The mass of 1 cubic meter of a substance is 800 kilograms under certain conditions, what is the volume, in cubic centimeter, of 1 gram of this substance under these conditions?

(1 kilogram = 1,000 grams & 1 cubic meter = 1,000,000 cubic centimeters)

1m3 = 800 kg => 100000 cm3 = 800 X 1000 gms

canceling zeros
10 cm3 = 8 gms
1 gm - = 10/8 cm3 = 1.25 cm3
