Question

A swimming pool is 260m long and 140m wide.If 54600
cubic metres of water is pumped into it,find the height of water in the level in it.

Answer 1

Heya!!!

Sol:
Length of the swimming pool = 260 m
Breadth of the swimming pool = 140 m

Let the height of the water in the swimming pool after pouring water be h meters.

Volume of the water poured = 54600 m3

l x b x h = 54600
260 x 140 x h = 54600
h = (54600) / (260 x 140)
h = 1.5 m = 150 cm

Hence, the water level in the swimming pool is 150 cm.

Hope this helps you ☺☺

Answer 2

A swimming pool can be resembled as a cuboid.

We have,
Length of pool, l = 260m
Width of pool, b = 140m

Also,
Volume of the pool = l × b × h
Or 54600 = 260 × 140 × h
Or 54600 = 36400h
Or h = 54600/36400
Or h = 1.5
Or h = 1.5m

Hence, the swimming pool will be filled by 1.5 m when 54600m³ water is pumped.
