A swimming pool 9 m wide and 12 m long is 1 m deep on the shallow side and 4 m deep on deeper side. Find the volume of the swimming pool?
Answer & explanation
Correct answer: option 3
Average height of the pool = \(\frac{4\;+\;1}{2}\) = \(\frac{5}{2}\)
Now,
Volume of the pool = Length × Breadth × Avg. Height
= 12 × 9 × \(\frac{5}{2}\) = 270 cubic m
