no he doesnt have enough resources to make the concrete mix.

So for every 1 unit of cement, you need 3 units of sand and 5 units of gravel.
required cement = 1/9 * 180kg = 20 kg (required cement to make 180 kg of concrete)
required sand = 3/9 * 180 = 60 kg (required sand to make 180kg of concrete)
required gravel = 5/9 * 180 = 100 kg ( required gravel to make 180kg of concrete)

Talil has 15kg of cement which is below the required amount, has enough amount of sand and has the exact amount of gravel need to make 180 kg of concrete

Hope it helps :smile:
