An object whose dimensions are 2cm by 4cm by 5cm has a mass of 25kg.

1. What is the volume of the object (2 marks)
2. Determine the density of the object in g/cm³ (2 marks)

Suggested resposponses

a) volume=volume of a cuboid

Volume= 2cm×4cm×5cm 

               =40cm³ ;

b) density= mass/volume

                  Change mass in kg to g

            25kg×1000= 25000g 

    Density= 25000g÷40cm³

                   =625 g/cm³...
