A swimming pool whos surface forms a rectangle measures 25 m long by 15 m wide The pool is 2 m deep at the shallow end and the depth increases at a constant rate to 4 m deep at the other end How many cubic meters of water will pool hold
a)1250 b)975 c)1000 d)1125

• Ans: d) 1125
  Pool Dimensions:
  Length 25 metres Width 15 metres Depth 2 metres to 4 metres (average 3 metres) Volume = 25 × 15 x 3 = 1125 cubic metres.

• probably 1125 i.e (25*15*3)=1125 (taking 3 as the avg height)

• Letz divide the pool into two parts
  1st part is the cuboid and 2nd is a cuboid with a triangular base, adding thei respective volume gives the net volume,
  volume1=25*15*2=750
  volume2=1/2*25*2*15=375
  net volume= 750+375=1125

• D) 1125 , (25*15*2) + (25*15*2)/2

• option should be multiple of 25*15, hence option d> is correct

• volume1=l*b*h=25*15*2=750
  volume=l*b*h/2=750/2=375
  total=volume1+volume2=1125

• l=25
  b=15
  intialally deep=2
  after it increases at 4m deep
  avg of deep=2+4/2=3
  volume=l*b*h=
  25*15*3
  =1125
