Carbon kids math quiz for schools competition

Deco-Carbon holds (sequesters) 59% carbon minimum in its structure. If you calculate the population of your town or city and divide it by 4.3 persons per household, but allowed only one car per household, how many cars are in your town or city?

Now consider what would happen if every household was to buy one 10kg bag of Deco-Carbon for their garden or pot plants. How many cars CO2 output in one year would your town or city offset by using Deco-Carbon?

Put your school in the draw to win 1 Ton of Deco-Carbon garden treatment for your school by working out this math quiz for your town or city.

Base your answer on these key factors:

Density of petrol: 737kg per cubic metre

Fuel economy of typical car: 10 litres per 100 km

Assume the typical km driven per car per year is 20,000 km

Percentage carbon in petrol is 85% by weight

Carbon sequestered by every 10kg bag of Deco-Carbon at 59% carbon

Summit your answer by emailing your name, your schools name and contact details to info@rcra.com.au

Good Luck!
