Question

a block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. it has a mass of 213 g. what is its density? a. 638 g/cm3 b. 6240 g/cm3 c. 0.0773 g/cm3 d. 7.89 g/cm3

Answer 1

Volume = 3 cm × 3cm × 3cm
             =  27 cm ³

Mass  =  213 g

Density  =  $\frac{MASS}{VOLUME}$
 
              = $\frac{213 g}{27 cm ^{3} }$
 
              =  7.89 g / cm³

Thus answer is D.

Answer 2

Don't read, the answer is D
