a swimming pool is 40m long 25m wide 6m deep find a cost of cementing of its floor and walls at the rates of ₹135 square per meter
surface area = base + 4 sides
= 40(25) + 2(40)(6) + 2(25)(6) m^2
= .....
Once you have the total surface area, multiply that by your cost of 135 per square metre.
To find the cost of cementing the floor and walls of the swimming pool, we need to calculate the surface area of both the floor and the walls separately.
1. Calculating the surface area of the floor:
The floor of the swimming pool is a rectangular shape, so we can calculate its surface area using the formula:
Area = Length * Width
Given that the length of the swimming pool is 40m and the width is 25m, we can calculate the floor area as follows:
Area of the floor = 40m * 25m
2. Calculating the surface area of the walls:
The walls of the swimming pool form a rectangular prism shape (excluding the floor), so we need to calculate the area of each side separately. Since the height of the pool is 6m, the area will be the same on all four sides.
Area of one side = Length * Height
Area of the walls = 2 * (Length * Height) + 2 * (Width * Height)
Given that the length of the swimming pool is 40m, the width is 25m, and the height is 6m, we can calculate the wall area as follows:
Area of the walls = 2 * (40m * 6m) + 2 * (25m * 6m)
3. Calculating the total surface area:
To find the total surface area, we need to add the floor area and the wall area together:
Total surface area = Area of the floor + Area of the walls
4. Calculating the cost:
Given the rate of ₹135 per square meter, we can multiply the total surface area by this rate to find the cost:
Cost = Total surface area * Rate (₹135 per square meter)
Now that we have explained how to calculate the cost, let me calculate the actual cost for you.
