in a minute?​

Answer 1

Correct Question :-

A river 3m deep and 40 m wide is flowing at the rate of 2 km / hr. How much water will fall into the sea in a minute?

$\bf{Given\:: }$

• Height = 3 m

• Breadth = 40 m

• Length = 2km = 2000 m

• Time = 1 h = 60 mins

$\rightarrow{ \bf{\sf \: Water / hour = \frac{2000}{60} }}$

$\rightarrow{ \bf{\sf \: \frac{100}{3} }}$

$\orange\rightarrow \orange{\boxed{ \bf{\sf \:Volume = l \times b \times h }}}$

$\rightarrow{ \bf{\sf \: \frac{100}{3} \times 3 \times 40 = 4000 m³}}$

$\red{\bf{ \sf 4000 \: {litres}^{3} }}$
