Answer 1

$\large\mathfrak \pink{Solution:-}$

$\underline \mathbb{GIVEN:-}$

★Length (l) = 150 metres

★Breadth (b) = 100 metres

★Height (h) = 3 metres

★Dimension of the pipe =  2 dm × 1.5  dm

★Velocity  of the water = 15 km / hr

$\underline \mathbb{TO \: FIND:-}$

Time required to fill the tank into 3 metres deep.

$\underline \mathbb{FORMULA:-}$

Volume of a cuboid (tank)  = length × breadth × height.

1 decimetre = 0.1 metre and 1 kilometre = 1000 metres

$\underline \mathbb{BY \: THE \: PROBLEM:-}$

$Volume \: of \: the \: tank \: = length \times breadth \: \times height \\ \\ \implies \: Volume \: of \: the \: tank \: \: =( 150 \times 100 \times 3) {m}^{3}\\ \\ \implies \: Volume \: of \: the \: tank \: 45000 = {m}^{3}$

$Volume \: of \: water \: pass \: through \: pipe \: in \: 1 \: hour \: \\ \\ \implies0 .2 \times 0.15 \times 15000{m}^{3}\\ \\ \implies450m {}^{3}$

$Time \: required = \frac{45000}{450} = 100 \: hours$

$\underline \mathbb{ANSWER:-}$

$\boxed{100 \:hours\: required\: to\: fill \:the \:tank\: into \:3 \:metres \:deep.}$
