Question

2.5 m³ of marble has a mass of 6775 kg.

3
a) Calculate the density of marble in kg/m³.
b) Find the mass of 1.9 m³ of marble in kg.

Answer 1

Answers:

a) 2710 kg/m³

b) 5149 kg

====================================================

Work shown for part a)

density = mass/volume

density = (6775 kg)/(2.5 m³)

density = (6775/2.5) kg/m³

density = 2710 kg/m³

-----------------------------------

Work shown for part b)

density = mass/volume

mass = density * volume

mass = (2710 kg/m³) * (1.9 m³)

mass = (2710*1.9) kg

mass = 5149 kg
