If 2 objects have the same volume of 10cm3 and object A has a mass of 2 grams and object B has a mass of 4 grams, how do their densities relate to one another?



I need a step by step explanation also. I don’t fully understand the subject. I also need an answer ASAP. This is due tomorrow and my teacher will not give me extra time even though I was excused.

Explanation:

density =mass / volume

now, when the mass of an object increases the volume of the object will decrease when density is kept constant.

so if an A object has a higher mass than object Bs mass which has same density, than object B will have higher volume than object A.

in other words mass and volume is indirectly proportional when density is kept constant

Answer:

density of object B is double that density of object A

Explanation:

Density is calculated as follows:

density = mass / volume

then,

density of object A = 2 grams / 10 cm³ = 0.2 g/cm³

density of object B = 4 grams / 10 cm³ = 0.4 g/cm³

The relation between them is:

density of object B / density of object A  =  0.4 / 0.2 = 2
