Question

A swimming pool is 50 m in length, 30 m in breadth, and 2.5 m in depth. find the cost of cementing its floor and walls at the rate of rupees 27 per square metre?

Answer 1

51,300 rupees

Explanation:

Surface area of the 2 short walls = 2 x 30 x 2.5 = 150

Surface area of the 2 long walls = 2 x 50 x 2.5 = 250

Surface area of the floor = 50 x 30 = 1500

Total surface area = 150 + 250 + 1500 = 1900 m²

27 rupees/m² x 1900 m² = 51300 rupees
