<span>∵ There is a proportional relationship between the mass and the volume of the places of metal.
Let volume = v and mass = m
So, the relation between volume and mass will take the form:
        v = km
where k is constant and can be calculated as follow:
when m = </span><span>34.932 , and v = 4.1   ⇒⇒⇒ k = v/m = 0.117371
</span>when m = 47.712<span> , and v = 5.6   ⇒⇒⇒ k = v/m = </span>0.117371
when m = 61.344 , and v = 7.2   ⇒⇒⇒ k = v/m = <span>0.117371
when m = </span>99.684 , and v = 11.7  ⇒⇒⇒ k = v/m = <span>0.117371

∴ v = 0.117371 m
</span>
For  v =<span>15.3
∴ m = v/k = 15.3/0.117371 = 130.356 </span><span>gram

</span>The mass of a piece of this metal that has a volume of 15.3 cubic centimeters ≈ 130.4 gram (<span>round to the nearest tenth</span>)

The Sahara Desert has an area of approximately 9 400 000 km^2. While estimates of its average depth vary, they center around 150
Andrew [12]

Answer:

a). 1.128\times 10^{25} grains

b). \frac{1}{8000}

c). 6.54305\times 10^{7} years

Step-by-step explanation:

a). Given Sahara desert has an area of approximately = 9400000 km²

= 9400000×(10000000000) cm²

= 9.4\times 10^{16} cm²

Depth of the desert = 150 m

= 15000 cm

Volume of desert = Area × Depth

= 9.4\times 10^{16}\times 15000

= 1.41\times 10^{21} cm³

Since 1 cm³ holds sand grains = 8000

Therefore, Grains in Sahara Desert = 1.41\times 10^{21}\times 8000

= 1.128\times 10^{25}

b). Since 1 cm³ = 8000 grains

1 grain = \frac{1}{8000} cm³

c). A truck can carry sand = 20.5 m³ Or 20.5\times (10^{2})^{3} cm^{3}

= 2.05\times 10^{7} cm³

Now time taken to recreate Sahara Desert = \frac{\text{Total amount of sand}}{\text{Sand in one truck}}\times 30 seconds

=  \frac{1.41\times 10^{21}}{2.05\times 10^{7}}\times 30

= 20.6341463\times 10^{14} seconds

= \frac{20.6341463\times 10^{14} }{365\times \times 24\times 3600} years

= 6.54305\times 10^{7} years
