Question

A swimming pool is 20m long. 15m board and 2.5m deep . what is the volume of the pool​

Answer 1

Answer:

Volume of swimming pool is 750 cu.m

Step-by-step explanation:

Given,

Length of swimming pool = 20 m

Breadth of swimming pool = 15 m

Height of swimming pool = 2.5 m

Volume of swimming pool = (l×b×h) cu.m

= (20×15×2.5) cu.m

= 750 cu.m

Hence, Volume of swimming pool is 750 cu.m

Answer 2

Answer: Rs.5600

Explain:

Given length of swimming pool =20m

Breadth of swimming pool =15m

Height of swimming pool =4m

Curved surface area of cuboid =2(l+b)h

=2[20+15]×4

=2×35×4

CSA of cuboid (pool)=280m

2

If cost of painting is =20 Rs/sq. m

then cost of painting four walls of pool =20×280

Cost =5600Rs.

Hence cost of painting four walls of swimming pool is Rs. 5600.
