A bricklayer needs to order 6300kg of building sand

luda_lava [24]

Answer:

$9\times 10^7\ \text{grains of sand}$

Step-by-step explanation:

Given that,

A bricklayer needs to order 6300kg of building sand.

1 grain of this sand weighs $7\times 10^{-5}\ kg$ .

We need to find how many grains of sand are there in 6300 kg.

It can be just calculated as follows :

1 grain of sand = $7\times 10^{-5}\ kg$

$6300\ kg=\dfrac{6300}{7\times 10^{-5}}\\\\=9\times 10^7\ \text{grains of sand}$

= 90000000 grans of sand

So, 6300 kg is equal to $9\times 10^7\ \text{grains of sand}$ .
