Answer 1

Given :

Dimensions of the four walls of an auditorium = 18.4 m × 12.6 m × 11.5 m

The cost of painting per m² = Rs. 38

To find :

Cost of painting the four walls

According to the question,

We know,

Lateral surface of cuboid = 2(l + b) × h

Where,

l = Length

b = Breadth

h = Height

➞ Lateral surface area of cuboid = 2(l + b) × h

➞ Lateral surface of cuboid = 2(18.4 m + 12.6 m) × 11.5 m

➞ Lateral surface area of cuboid = 2(31 m) × 11.5 m

➞ Lateral surface area of cuboid = 2(356.5) m²

➞ Lateral surface area of cuboid = 713 m²

So, the lateral surface area of cuboid is 713 m².

Now,

➞ Cost of painting = Rs. 38 × 713

➞ Cost of painting = Rs 27,093

So, the cost of painting the four walls is Rs. 27,094.
