The cost of square slab is proportional to its thickness and also proportional to the square of its length. What is the cost of a square slab that is 3 meters long and 0.1 meter thick?
1) the cost of square slab that is 2 metes long and 0.2 meter tick is 160$ more than the cost of a square slab that is 2 meters long and 0.1 meter thick
2) the cost of square slab that is 3 metes long and 0.1 meter tick is 200$ more than the cost of a square slab that is 2 meters long and 0.1 meter thick
OA is D
