Final answer:
The mass of the object is 36 g. Option A is correct.
Step-by-step explanation:
The question is about calculating the mass of an object given its density and volume. Density is a measure of how much mass is contained in a given volume. It is typically expressed in units of grams per cubic centimeter (g/cm³). Volume is a measure of the amount of space an object occupies. It is typically expressed in units of cubic centimeters (cm³).
The density of an object is defined as its mass per unit volume. Therefore, we can use the following formula to calculate the mass of an object:
mass = density × volume
In this case, the density of the object is 7.2 g/cm² and the volume of the object is 5 cm³. Substituting these values into the formula, we get:
mass = 7.2 g/cm² × 5 cm³
mass = 36 g
Therefore, the mass of the object is 36 g. Option A is correct.
