Question

a pit 5cm long and 3.5m wide is dug to a certain depth . if the volume of the taken out of it is 14cm3 , What is the depth out of it.

Answer 1

Hi there !!

We are given that :

Length = 5 cm

Breadth = 3.5 m = 350 cm

Height = ?

SO ,
Here the pit is in the shape of a cuboid.

We are given the volume of the pit as 14 cm³

We know that

Volume of a cuboid = lbh

14cm³ = 5 × 350 × h


Height , h = $\frac{14}{5*350}$

= 0.008 cm

SO,
depth of the pit = 0.008 cm

Answer 2

Given,

Length = 5 cm

Breadth = 3.5 m

= 350 cm

Volume = 14 cm³

Volume of cuboidal pit = l * b * h

Here, h = depth

14 = 5 * 350 * h

14 = 1750 * h

h = 14 / 1750

h = 0.008

Depth = 0.008 cm Ans.
