Question

A rectangular block of copper metal weighs 1896 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, what is the density of copper? Please round to the second decimal place.

Answer 1

Answer:

Density = 8.92 g/cm³

Explanation:

Density shows the relation of the mass and volume of a determined object. We have this deffinition:

Density = mass / volume

First of all, we calcualte the volume of the block of copper metal, with the data given:

8.4 cm . 5.5 cm . 4.6 cm = 212.52 cm³

Now we replace at the density formula:

Density = 1896 g /212.52 cm³  = 8.92 g/cm³
