Question

A pit 5 m long and 3.5 m wide is dug to a certain depth. if the volume of earth taken out of it is 14 m cube, what is the depth of the pit ??

Answer 1

Hi ,

Dimensions of the pit are ,

Length = l = 5 m

Width = w = 3.5 m

Let the depth of the pit = h m

Volume of the cubiod= volume of the

earth taken out

lwh = 14 m³

5 m × 3.5 m × h = 14 m³

h = ( 14 )/ ( 5 × 3.5 )

After cancellation,

h = 0.8 m

Therefore,

Depth of the pit = h = 0.8 m

I hope this helps you.
