Density is defined as the ratio of mass to volume. In this case, the mass of the oil is given as 22 pounds and the volume is given as 2/5 cubic foot.
Therefore, the density of the oil is calculated as:
Density = Mass / Volume
Density = 22 pounds / (2/5) cubic foot
To divide by a fraction, we multiply by its reciprocal:
Density = 22 pounds * (5/2 cubic foot)
Simplifying:
Density = 110 pounds / 2 cubic foot
Final Answer: The density of the oil is 55 pounds per cubic foot.
Density is the ratio of a substances mass to its volume. A 2/5 cubic foot container of oil has a mass of 22 pounds. What is the density in pounds per cubic foot, of the oil?
