Question

. A swimming pool is 36 metre long, 12 metre wide and 1.5 metre in depth. Find the

cost of cementing its floor and four walls at the rate of rupees 35 per metre square​

Answer 1

Answer:

Rs. 8540

Step-by-step explanation:

Area of four walls = Lateral Surface Area

Lateral Surface Area of cuboid = 2(l+b)h

= 2(36 +12) 1.5

= 48×3

= 244 m²

Cost of cementing per metre square = Rs. 35

Cost of cementing 244 m² = 244×35

= Rs. 8540
