Answer:
The cost to gold plate a rectangular lid with dimensions 10cm by 24cm at a cost of £6 per cm² is £1,440.
Explanation:
To calculate the cost of gold plating for the rectangular lid, we first need to determine the total surface area of the lid. The fornula for the surface area of a rectangle is length times width, so:
Surface Area = length x width
Surface Area = 10cm x 24cm
Surface Area = 240cm²
Now that we knpw the surface area, we can calculate the cost of gold plating. The cost is given as £6 per cm², so we just need to multiply the surface area by the cost per cm²:
Cost = Surface Area x Cost per cm²
Cost = 240cm² x £6/cm²
Cost = £1,440
Therefore, it will cost £1,440 to gold plate the rectangular lid with dimensions 10cm by 24cm at a cost of £6 per cm².
