Correct answer: B. 40

Mass, aligned & M=d V & d=(M)/(L^3) & d=4 ~g/ cm^3 aligned If unit of mass is 100 ~g and unit of distance is 10 ~cm . So, density aligned y & = 4( 100 ~g 100 ) ((10)/(10) ~cm)^3 & =(((4)/(100)))/(((1)/(10))^3) · (100 ~g) (10 ~cm)^3 & =40 ~g ~cm^ -3 aligned Aliter aligned u_2 & =u_1((M_1)/(M_2))((L_1)/(L_2))^ -3 & =4((1)/(100))((1)/(10))^ -3 & =40 aligned
