Question

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

Answer 1

$\red{\textbf{Answer :- 0.8m}}$

Step-by-step explanation:

$R.E.F image,$

$L= 5m$

$W = 3.5m$

$volume \: of \: pit = 14 {m}^{3}$

$volume = l \times b \times h$

$14 = 5 \times 3.5 \times h$

$h = \LARGE \frac{14}{5 \times 3.5}$

$= 0.8m$

$height \: of \: the \: pit \: = 0.8m$

• Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box.

• Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.

• If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches. (Cubic inches can also be written in^3.)
