Question
A cuboidal box with dimensions 12.5 cm (length), 7.5 cm
(breadth), and 10 cm (height) is open from the top. The box is to be painted from the outside. If the cost of painting is Rs. 2 per cm², calculate the total cost of painting the box.Solution
Area to be painted = lateral surface area of cuboid + base area of cuboid = 2 X (length + breadth) X height + length X breadth = 2 X (12.5 + 7.5) X 10 + 12.5 X 7.5 = 400 + 93.75 = 493.75 cm2 Therefore, cost of painting = 493.75 X 2 = Rs. 987.50
