To find the cost of 400g of rice given that a kilogram (1000g) costs $6, we can use the following steps:

Step 1: Determine the cost per gram of rice.
To find the cost per gram, divide the total cost by the total weight. In this case, the total cost is $6, and the total weight is 1000g.
Cost per gram = Total Cost / Total Weight
Cost per gram = $6 / 1000g

Step 2: Calculate the cost of 400g of rice.
Multiply the cost per gram by the weight of the rice we want to find the cost of. In this case, we want to find the cost of 400g of rice.
Cost of 400g rice = Cost per gram x Weight of rice
Cost of 400g rice = (Cost per gram) x 400g

Let's perform the calculation:

Cost per gram = $6 / 1000g = $0.006
Cost of 400g rice = $0.006 x 400g = $2.40

Therefore, the cost of 400g of rice is $2.40.
