Answer:

$1.128048 \times 10^{25}$ an estimate of grains of sand within the Sahara Desert

Step-by-step explanation:

Parameters:

The Sahara Desert spans an approximate area of 9,400,400 sq.km.

Average depth is around 150 m

Objective: Finding the approximate quantity of grains of sand in the Sahara Desert

Solution:

Area of Sahara desert = 9,400,400 sq.km.

$1 km^2 = 1000000 m^2$

Therefore, $9,400,400 km^2 = 1000000 \times 9400400 m^2$

$9,400,400 km^2 =9.4004 \times 10^{12}m^2$

Volume of sand = $Area \times depth$

= $1.41006\times 10^{15} m^3$

$1 m ^3 = 1000000 cm^3$

Afterward, we estimate that

1 cubic cm contains around grains of sand = 8000 $1.41006 \times 10^{21}cm^3$ $1.41006 \times 10^{21} \times 8000$

which gives us the total amount of grains = $1.128048 \times 10^{25}$

= $1.128048 \times 10^{25}$

Hence we approximate the grains of sand present in the Sahara Desert[[TAG_74]]
