Answer 2

Answer:

Explanation:

Density = Mass/Volume

Let mass be x

= x/10cm^(-3) = 15 gcm^(-3)

or, x = 15 x 10= 150 g

SI unit of density- Kg/m^3 or Kgm^(-3)

Relation between gcm^-3 and kgm^-3:

1 g/cm^3 = 1/1000/1/100x1/100x1/100 kg/m^3

= 1/100 divided by 1/1000000

1/100 x 100000/1 = 1000 Kgm^3

Hence, to convert gcm^3 to kgm^3 we multiply by hundred and vice-versa

So, 15 gcm^-3 = 15000 kgm^-3

Volume = 10 cm = 10/100 m (ans)
