A) 900 \[metr{{e}^{3}}\]
B) 456 \[metr{{e}^{3}}\]
C) 942 \[metr{{e}^{3}}\]
D) 924 \[metr{{e}^{3}}\]
Correct Answer: B
Solution :
(b): The cross section of swimming pool is like a trapezium, of which parallel sides are \[4\frac{1}{2}\] metres and \[1\frac{1}{2}\]metres and vertical perpendicular is 32 metres \[\therefore \]Area of cross section \[=\frac{1}{2}\times 16\times \left( 4\frac{1}{2}+1\frac{1}{2} \right)=48\]sq. m. \[\therefore \]Volume of water in swimming pool = Area of cross section \[\times \]Length \[=48\times 9.5=456\]cubic metres.You need to login to perform this action.
