15. The dimensions of a swimming pool are 30 m
long, 20 m wide, and depth 9 m. If 1800 KL of
water is already filled in the pool, then,
a. Find the height of the water in the pool now.
b. How many more litres of water is required to fill
the pool up to a height of 8 m only?

Given : The dimensions of a swimming pool are 30 m long, 20 m wide, and depth 9 m.
1800 kL of water is already filled in the pool
To Find : a. Find the height of the water in the pool now.
b. How many more litres of water is required to fill the pool up to a height of 8 m only
Solution:
height of the water in the pool when 1800 kL of water is already filled in the pool = h
Volume of Water = 30 x 20 x h m³
= 600h m³
1 m³ = 1000 L
= 600h * 1000 L
= 600h kL
600h = 1800
=> h = 3 m
height of the water in the pool when 1800 kL of water is already filled in the pool = 3 m
more litres of water is required to fill the pool up to a height of 8 m only
= (30 x 20 x 8 - 30 x 20 x 3) kL
= 3000 kL
3000 kL more litres of water is required to fill the pool up to a height of 8 m only

Answer:
3000 cm
Step-by-step explanation:
Volume of water = L×B×H
=20×30×h m³
=600h m³
1m³ = 600h
600h = 1800kl
= 1800/600
=3cm³
b. Volume = L×B×H
Height = 8-3
=5
=600×5=3000
