Answer 2

CORRECT QUESTIONS : -

A river 2 m deep and 45 m wide is flowing at the rate of 3 km/hr.find the quantity of water that run in to the sea per minute

given,

h = 2 m

b = 45 m

Find ,

find the quantity of water that run in to the sea per minute

REQUIRED ANSWER

GIVEN ,

$h = </strong><strong>2</strong><strong> \: m$

$b = 4</strong><strong>5</strong><strong> \: m$

➠ The water flowing river $= \frac{2km \times 1000}{1h \times 60}$

➠$l = \frac{2000}{60} = \frac{100}{2} \: m\m \:$

➠ $volumn \: of \: water \: fall \: into \: sea \: in \: min \: = l \times b \times h$

➠$\frac{100 \times 40 \times 3}{2}$$= 4000 \: m {}^{2} \:$

hence, proved :)

★ ADDITIONAL INFORMATION

➠ Volume = length × breadth × height

● Length of cuboid = Volume/(breadth × height)

● Breadth of the cuboid = Volume/(length × height)

● Height of the cuboid = Volume/(length × breadth)

➠ Volume of the cuboid = (Area of base) × (height of the cuboid) = (l × b) × h = lbh
