Tony Molina · Answer 1

Depth is 7.49cm

Explanation:

Given that;

The diameter of tube is (D) = 4.7cm

Area of the tube is = πD^2/4

Area is 3.142*4.7*4.7/4=17.35cm2

Mass (M) = 130g

Density = 1g/cm^3

Recall that Density = mass / volume

Hence volume = 130/1=130cm^3

Also note

Volume=area*depth

130=17.35*depth

Depth=130/17.35=7.49cm
