Problema Solution
Gold was mined in California and divided into 1.5kg pieces. each piece of gold was a perfect cube 8.1cm tall.What was the density of the gold?
Answer provided by our tutors
The formula for density is:
Density = Mass/Volume
In our case:
Mass = 1.5 kg
Volume = 8.1^3 cm^3 (volume of a cube with 8.1 cm length of each side)
Plug the values into density formula:
Density = 1.5/8.1^3
Density = 0.002822 kg/cm^3
The density of the gold was 0.002822 kg/cm^3.
