Question

A block of iridium has a length of 4.20 cm, a width of 3.80 cm and a height

of 5.40 cm. The mass of the block is 1800 g. Calculate the density.
the following formulas with its creator.

Answer 1

d = 20.89 g/cm³

Step-by-step explanation:

Given data:

Length of block = 4.20 cm

width of block = 3.80 cm

Height of block = 5.40 cm

Mass of block = 1800 g

Density of block = ?

Solution:

First of all we will calculate the volume.

V = l×w×h

V = 4.20 cm ×3.80 cm× 5.40 cm

v = 86.18 cm³

Density:

d =m/v

d =1800 g/ 86.18 cm³

d = 20.89 g/cm³
