Question

A block of metal has a volume of 13.4 in^3 and weighs 5.36 lb.
What is its density in grams per cubic centimeter?
Express the density in grams per cubic centimeter to three significant figures.

Answer 1

Answer:

2.5

Explanation:

13.4 by 5.36

Mass by volume

Answer 2

Answer:

11.1 grams per cubic cm

Explanation:

Volume = 13.4 in^3 = 219.587 cm^3

Mass = 5.36 lb = 2431.255 gram

$density = \frac{mass}{volume} \\ = \frac{2431.255}{219.587} \\ = 11.0719441 \\ \approx \: 11.1 \: grams \: per \: {cm}^{3}$
