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?
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.
