A bricklayer needs to order 6300 kg of building sand.

a) Write 6300 kg in grams, giving your answer in standard form.

One grain of this sand approximately weighs [tex]7 \times 10^{-1}[/tex] g.

b) How many grains of sand are there in 6300 kg of sand? Give your answer in standard form.

Converting 6300 kg to grams, we multiply by 1000 (since there are 1000 grams in a kilogram), giving us 6300000 grams. Written in standard form, this is 6.3 x 106 grams.

To find the number of grains in 6300 kg of sand, we again use the weight in grams (6.3 x 106 grams) and divide by the weight of one grain of sand, which is given as 7 x 10-1 grams. This calculation gives us:

(6.3 x 106) / (7 x 10-1) = 9 x 106 grains of sand.

Thus, there are 9 x 106 grains of sand in 6300 kg of building sand when considered in standard form.
