The Volume can be determined by the formula

V = (mass)/(density)
So,
V1 = 9/10 = 0.9 cm^3
V2 = 4/10 = 0.4 cm^3
V1 - V2 = 0.5 cm^3
THe answer will be "Object A, by 0.5 cubic centimeter."

Answer:

Object A, by 0.5 cubic centimeter

Step-by-step explanation:

Density (d) is given by :


d=(m)/(V)

m is the mass of an object

V is its volume

For object A:


V_1=(m_1)/(d_1)


V_1=(9\ g)/(10\ g/cm^3)=0.9\ cm^3...........(1)

For object B:


V_2=(m_2)/(d_2)


V_2=(4\ g)/(10\ g/cm^3)=0.4\ cm^3...........(2)

From equation (1) and (2) it is clear that volume of object A is greater by 0.5 cm³. So, the correct option is (b) "Object A, by 0.5 cubic centimeter".
