340cm is correct answer hai

Answer 2

Answer:

12000 kg/m^3

Explanation:

Given,

The mass of gold (M) = 240 g

The volume of gold (V) = 20 cm³

Density =  

$\frac{mass}{volume} = \frac{M}{V} = \frac{240 g}{20 cm^3} = 12g/cm^3$

Since we need to keep the answer in SI unit,

The density of gold in SI unit is

$Since,\\1 g/cm^3 = 1000 kg/m^3\\\\12 gcm^3 = 12 g/cm^3 X 1000 = 12000 kg/m^3$
