Step-by-step explanation:
nyshakatiyar43:
It's first you have to find the volume i.e 2×4×5= 40 cm^3
then
As density is mass/ volume. Then the density of the cuboid = 100/ 40 = 2.5gcm^-3
then what is the answer ???
i can't understand
option is (A)1000kg m-cube (B)3000kg m-cube (C)5000kg m-cube (D)2500kg m-cube

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
