Question

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

Answer 1

Answer:

length of canal is 0.015 cm

Step-by-step explanation:

we know that volume of the canal is 240 cm cube

and its breadth = 2m = 200cm and height = 8dcm = 80 cm ( let the length of canal as l )

so formula of volume of canal = length * breadth * height

now put all required values

volume = l * B * H

240 cm^ 3 = l * 200 cm * 80 cm

240 cm ^ 3 = l* 16000cm^2

240cm^3 / 16000cm^2 = l

0.015 cm = l
