Question from UPSC Prelims 2021 CSAT Paper

Explanation : 

The volume of a cube is calculated by multiplying the length of one side by itself twice. In this case, the side of the cube is 1 meter, so its volume is 1 x 1 x 1 = 1 cubic meter. Since there are 1000 liters in a cubic meter and 1000 milliliters in a liter, there are 1000 x 1000 = 1000000 milliliters in a cubic meter. So the correct answer is (d) 1000000.
