Question

A $8m57cm$ pole was put in a pond to measure its depth.

If $4m66cm$ of pole remained outside water, then the depth of the pond is?

Answer 1

Find the depth of the pond:

Given: Length of the pole is $8m57cm$and the length of the pole outside the pond is $4m66cm$

$1m=100cm\Rightarrow 1cm=\frac{1}{100}m$

$$\begin{gathered} 8m57cm=8+\frac{57}{100}=8.57m \\ 4m66cm=4+\frac{66}{100}=4.66m \end{gathered}$$

The length of the pole inside the pond is $\left(8.57-4.66\right)=3.91m$

Hence, the depth of the pond is $3.91m.$
