Question

A pit 7 m long and 2.5 m wide is dug to a certain depth If the volume of the earth taken out of it is 28 m ^3 what is the depth of the pit ? ​

Answer 1

Answer:

Step-by-step explanation

Since length, Breadth and Depth of the pit is mentioned assume it to be of cuboidal shape.

To find the Depth of pit we would take the following steps:

Let the Depth of pit be measuring h m.

As, Volume of Cuboid = l×b×h

Volume of pit. = l×b×h

Questioη:-

A pit 7 m long and 2.5 m wide is dug to a certain depth. If the volume of the earth taken out of it is 28 m³ what is the depth of the pit?

$\text{\large\underline{\orange{Gıѵєη :- :-}}}$

• Length of a cuboidal pit(l) = 7m
• Breadth or width(b) = 2.5m
• Volume of the pit = 28m³

$\text{\large\underline{\red{Tσ Fıηd :-}}}$

• depth of the pit(height = h)

$\text{\large\underline{\purple{Sσłυтıση :-}}}$

Let the depth of the pit be a.

• $\implies{\sf{28m^{3} = 17.5m \times a}}$

• $\implies{\sf{ \dfrac{28}{17.5}= a}}$

• $\implies{\sf{ 1.6m = a}}$

Height or Depth = 1.6m

Hence,the depth of the pit is 1.6m
