Answer 2

Answer:

Step-by-step explanation:

we know that

density= mass/volume

let us find out volume of the given cuboid first

  volume= length  x  breadth   x  height

              =   2 x 4 x 5 cm^3

             =40 cm^3

   density  =  100/ 40   g/cm^3

                 =  2.5 g/cm^3

to convert into kg/m^3

we know that 1 g/cm^3 = 1000 kg/m^3

therefore , 2.5 g/cm^3= 2.5 x1000 kg/m^3

                                      = 2500kg/m^3
