A rectangular swimming pool is $50 \meters$ long and $25 \meters$ wide. Its depth is always the same along its width but linearly increases along its length from $1 \meter$ at one end to $4 \meters$ at the other end. How much water (in cubic meters) is needed to completely fill the pool?

Solution:

The volume of cuboid will be

50 × 25× 1=1250

The volume of the portion below cuboid will be

\Area \of \triangle × \width =1/2 . 3 . 50 . 25=1875

.' .

Total volume

= 1875+1250= 3125
