Ans. 
The area of both sides of an object dipping into electrolyte can be calculated by finding the surface area of the object and multiplying it by 2.
• Calculate the surface area of the object by using appropriate geometric formulas (e.g. for a rectangular object, use length x width).

• Multiply the surface area by 2 to get the total area of both sides of the object.

• Ensure that the object is fully submerged in the electrolyte to
