What is the Cost of Whitewashing a Room of Dimensions 15m x 12m x 10m at Rs. 2.50 per square meter?

Introduction

Whitewashing a room can significantly enhance its appearance and bring a fresh, clean look. However, before embarking on such a project, it's essential to calculate the total cost accurately. This guide will walk you through the process of determining the cost of whitewashing a room of dimensions 15 meters x 12 meters x 10 meters at a rate of Rs. 2.50 per square meter (sq. m).

Step 1: Calculate the Wall Surface Area

In a rectangular room, the walls' surface area can be calculated as follows:

Area of the Four Walls

- Two walls of dimensions 15 meters (length) times; 10 meters (height) - Two walls of dimensions 12 meters (width) times; 10 meters (height)

Calculations

- Area of two 15 meter walls:
2 times; 15 times; 10 2 times; 150 300 sq. meters
- Area of two 12 meter walls:
2 times; 12 times; 10 2 times; 120 240 sq. meters
Total wall area:
300 sq. meters 240 sq. meters 540 sq. meters

Step 2: Calculate the Total Area to be Whitewashed

The ceiling, if applicable, can also be whitewashed. However, in this case, we will focus on the walls and consider the ceiling as a separate option.

- Area of the ceiling: 15 meters times; 12 meters 180 sq. meters

- Total area: If only walls are whitewashed, the total area is 540 sq. meters. If the ceiling is also whitewashed, the total area is 540 sq. meters 180 sq. meters 720 sq. meters.

Step 3: Calculate the Cost of Whitewashing

Given the rate of Rs. 2.50 per square meter, the cost can be calculated as follows:

Cost for Whitewashing the Walls Only

- Total wall area: 540 sq. meters
Rate of whitewashing: Rs. 2.50 per sq. meter
Cost: 540 sq. meters times; Rs. 2.50 per sq. meter Rs. 1350

Cost for Whitewashing the Walls and Ceiling

- Total area: 720 sq. meters
Rate of whitewashing: Rs. 2.50 per sq. meter
Cost: 720 sq. meters times; Rs. 2.50 per sq. meter Rs. 1800

Final Answer

- Cost for whitewashing the walls only: Rs. 1350
- Cost for whitewashing the walls and ceiling: Rs. 1800
You can choose the appropriate cost based on whether or not you are whitewashing the ceiling.

By following these steps, you can accurately estimate the cost of whitewashing your room and plan your budget accordingly.

Note: The calculations provided here are based on the specific dimensions and whitewashing rate given in the scenario. Adjust the calculations as per your specific requirements and local whitewashing rates.
