A tank 10m×5m×6m is full of water.The amount of water taken out to reduce the water level by one metre is
Consider a given tank of edge l=10m,b=5m and h=6m
water taken out to reduce the water level by one metre
then edge of reduce the water level are,
l=10m,b=5m and h=1m
Required volume=10×5×1m3=50m3
Hence, this is the answer.
