An open box is made of wood 5 cm thick. Its external dimensions are 2.55 m, 2.15 m and 1.05 m. What is the total cost of painting the inner surface of the box at ₹100 per cm2?

Question

Anonymous · Answer

To find the cost of painting the inner surface of the box, we first calculated the inner dimensions by subtracting the thickness from the external dimensions. Then we computed the inner surface area and multiplied it by the cost of painting per cm², resulting in a total cost of ₹18,635,000.
