Question

how do you calculate the volume of water in a lake? given is the area of the lake at 1.35 km2 and its depth is 4.0 m

Answer 1

Given

Area of lake = 1.35 square km

Depth = 4.0m

Find

Volume of water in a lake

Step-by-step explanation

Volume of water in a lake is given by

`area* depth`

first we have to make the units same

as we know 1 square km = 1000000

so , 1.35 square km = 1.35 * 1000000= 1350000 square meter

so , volume of water in a lake =

`\begin{gathered} volume=1350000*4 \\ volume=5400000\text{ }cubic\text{ meter} \end{gathered}`

Final Answer

Therefore , the volume of water in a lake is 5400000 cubic meter
