Solution

Dear student,

We know,
Density= mass/volume
Therefore,
mass = density×volume
we know ,
Density (iron) > density (wood)
Also given same volume for both
Therefore,
Mass(iron)>mass(wood)

Dear student, We know, Density= mass/volume Therefore, mass = density×volume we know , Density (iron) > density (wood) Also given same volume for both Therefore, Mass(iron)>mass(wood)
