Question

Object A has a mass of 10 g and a volume of 8 cm3. Object B has a mass of 10 g and a volume of 6 cm3. Which object has a greater density and by how much? Object A, by 2 grams per cubic centimeter Object A, by 0.42 gram per cubic centimeter Object B, by 2 grams per cubic centimeter Object B, by 0.42 gram per cubic centimeter

Answer 1

It’s D honey, Object B, by 0.42 gram per cubic centimeter

Answer 2

Mass of object A = 10g
volume of object A = 8cm³
Mass of object B = 10g
Volume of Object B = 6cm³
we use the following formula to calculate the density of object A and B.
Density = Mass / Volume
Density of Object A = 10g / 8cm³ = 1.25g/cm³
Density of Object B = 10g / 6cm³ =1.67 g/cm³
So the density of object B is greater than object A
and if we find the difference:
1.67 - 1.25 = 0.42
So the answer is; Object B, by 0.42 gram per cubic centimeter
