Question
The density of iron is 7.86 $\mathrm{g} / \mathrm{cm}^{3} .$ What is its density in pounds percubic inch $\left(1 \mathrm{b} / \mathrm{in}^{3}\right) ?$
Step 1
We know that 1 pound is equal to approximately 453.592 grams. So, we have: 7.86 g/cm³ * (1 lb / 453.592 g) Now, we need to convert cubic centimeters to cubic inches. We know that 1 inch is equal to 2.54 cm, so 1 cubic inch is equal to (2.54 cm)³ = 16.3871 cm³. Show more…
