Q5 of 35 Page 74

In our Bokultala village, a canal is cut whose breadth is of 2m. and depth is of 8 dcm. If the total quantity of soil extracted is 240 cubic metre, then let us calculate the length of the canal.

Given , the breadth of the canal = 2m

And the depth of the canal = 8 dcm = m


As we know that 1m = 1000 dcm


Volume of the canal = 240 cubic m


We know that volume = area × length


⇒ 240 = 2 × × length


⇒ length =


⇒ length = 150000 dcm = 15 m
