Question

the mass of a solid rectangle block of iron is 23.6g and its dimensions are 2.1cm * 1.2cm * 1.1cm. calculate the density of iron

Answer 1

density = mass / volume
therefore density = 23.6 / 2.1*1.2*1.1
on solving we get 8.2 g/ c. c

Answer 2

Answer :

Density of iron = 8.51 g / cm³

Step-by-step-explanation:

Given,

Mass of rectangle block of iron = 23 .6 g

Dimensions of box = 2.1 cm * 1.2 cm * 1.1 cm

As we know,

$Density = \frac{Mass}{Volume}$

Volume = Length * Breadth *  Height

Volume = 2.1 * 1.2 * 1.1

Volume = 2.772 cm³

Now,

$Density = \frac{Mass}{Volume}$

Density = $\frac{23.6}{2.772}$

Density = 8.51 g / cm³

Hence,

Density of iron = 8.51 g / cm³
