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.

d = 20.89 g/cm³

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

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
