A cube of metal weighs 99.98 N and measures 0.18 m on each side. What is the density of the metal in kg/m^3? Round your answer to the nearest whole number.

Answer 1

Density of metal ρ= m/V, where m is mass in kg and V is volume in m³.

Wehave by conditions m = w/g where w = 99.98 N is waight in newtons and g = 9.8 m/sec² accelaration of gravity.

V = l³, where l = 0.18 m.

So ρ = (w/g)/l³ = (99.98N/9.8m/sec³)/(0.18m)³ = 1749 kg/m³.

Answer: ρ = 1749 kg/m³;

Answer 2

Calculate the volume

Convert the N to kgs

Set up the ratio kg/m³
