Step-by-step explanation:
a). Given Sahara desert has an area of approximately = 9400000 km²
= 9400000×(10000000000) cm²
=
cm²
Depth of the desert = 150 m
= 15000 cm
Volume of desert = Area × Depth
= 
=
cm³
Since 1 cm³ holds sand grains = 8000
Therefore, Grains in Sahara Desert = 
= 
b). Since 1 cm³ = 8000 grains
1 grain =
cm³
c). A truck can carry sand = 20.5 m³ Or 
=
cm³
Now time taken to recreate Sahara Desert =

= 
=
seconds
=
years
=
years
