A swimming pool is 20m in length, 15 m in breadth, and 4 m in depth.Find the cost of cementing its floor and walls at the rate of Rs 12 per square metres.
Volume of swimming pool= 20*15*4 = 1200 m3
1200 m3 = 112.92 m2
1 m2 = 12 Rs
so 112.92 = 112.92*12 = 1355.04 Rs
1200 m3 = 112.92 m2
1 m2 = 12 Rs
so 112.92 = 112.92*12 = 1355.04 Rs
