I know the answer,I just learned this,U measure it by hertz
Answer & Explanation:
volume of the block = 4.5 x 5 x 6 = 135 cm^3 also equal to 1.35 x 10^-4 m^3
USE THE FORMULA
<em>Density = mass / volume</em>
<em><u /></em>
<em><u>Answer in gcm^-3</u></em>
<em>Density = 1502 / 135</em>
<u>Density = 11.1 gcm^-3</u>
<em><u /></em>
<em><u>Answer in kgm^-3</u></em>
<em>Density = 1.502 / 1.35 x 10^-4</em>
<u>Density = 11125.9 kgm^-3</u>
