length = 12m ; breadth = 9m ; height = 4m
TSA of the tank = 2[length×breadth + breadth×height + height×length] = 2[12×9+9×4+4×12]
= 384 m2
Area of the rectangular iron sheet = 384 m2
so, length × breadth = 384 ⇒ length = 384 / 2 = 192 m [as sheet is 2 m wide]
Now total cost of the sheet = Rs. (192 × 50) = Rs. 9600
