Mass of 23.94kg and volume 2.10 cubic centimeters. Calculate the density of the copper wire in si units (ų/mm cubic)
Kamila [148]

Answer:

Density = 1.14 kg/mm³

Explanation:

Given the following data;

Volume = 2.10 cm³ to mm = 2.10 * 10 = 21 mm³

Mass = 23.94kg

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

Density = \frac{mass}{volume}

Substituting into the equation, we have;

Density = \frac{23.94}{21}

Density = 1.14 kg/mm³
