Answer 2

Answer:

0.1m

Step-by-step explanation:

$\implies$ $Volume\:of\:well=l×b×h$

$\implies$ $V=14×5×6$

$\implies$ $Volume\:of\:well=420\:m^{3}$

As the soil from well is used on rectangular field it will be in the form of cuboid.

$\implies$ $Volume = l×b×h$

$\implies$ $h=\Large\frac{V}{l×b}$

$\implies$ $h=\Large\frac{420}{70×60}$

$\implies$ $\boxed{h=0.1\:m}$
