General guidance

Concepts and reason

Volume: It is the quantity of space that a compound occupies. It is generally expressed in cubic meters.

Density ( ): It is the mass that is present per unit volume of a substance. SI unit is

Fundamentals

…… (1)

Conversion factor:

Step-by-step

Step 1 of 2

The conversion factor for

Then:

Centimeter and inches are units of length, and it is reported that is equal to . Therefore, will be equal to , and detailed calculations are given in step-1.

Ensure that the proper conversion factor is used.

Correct:

Incorrect:

Convert density into.

Step 2 of 2

The density of aluminum is given as .

Conversion factor

Therefore:

It is calculated that .

Substitute these values in Equation (1).

The density of aluminium expressed in pounds per cubic inch is calculated as.

Using the conversion factor, the volume of aluminum is equivalent to and in inches it is calculated as. From density, mass of aluminum per in pounds is calculated as. On substituting these values, the density of aluminium expressed in pounds per cubic inch is calculated as.

Ensure that density is expressed in proper units.

Correct: The density of aluminium expressed in pounds per cubic inch is calculated as.

Incorrect: The density of aluminium expressed in pounds per cubic inch is calculated as.

Answer
