The question is incomplete, complete question is:
A fluid occupying
of volume has a mass of 4 Mg. Calculate its density and specific volume in SI, EE, and BG units.
Explanation:
1) Mass of liquid = m = 4 Mg = 4 × 1,000 kg = 4,000 kg
(1 Mg = 1000 kg)
Volume of the fluid = V = 
Density of the fluid = D

Specific volume is the reciprocal of the density :

Specific volume of the fluid = 

2)
Density of the fluid in English Engineering units = D 
1 kg = 2.20462 lb
1 m = 3.280 ft

Specific volume of the fluid :

3)
Density of the fluid in British Gravitational System units = D 
1 kg = 0.06852 slug
1 m = 3.280 ft

Specific volume of the fluid :
