Given,
Capacity of the cuboidal water tank = 60,000 Litre
We know,
1000 Litre = 1m³
60,000 Litres = 60000/1000 m³= 60m³

Volume = 60m³

Length (l) = 2.5m
Height (or depth) (h)= 12m
Let the breadth be ' b '

Volume = l × b × h

60 = 25/10 × b × 12

$\frac{60 \times 10}{25 \times 12} = b$
b = 2

Thus, the breadth of the tank is 2m

Given, a river 3m deep and 40m wide is flowing at the rate of 2km per hour.

Area of cross section of the river = 3 * 40 = 120 m²

Now, volume of water flowing through this cross section in every minute = Area * rate

= 120 * 2 km/hr

= 120 * (2000/60) m/min

= 2 * 2000

= 4000 m³

Since 1 m³ = 1000 litres

So, 4000 m³ = 4000 * 1000 litres = 4000000 litres

So, in 1 minute, water will fall into the sea is 4000000 litres.

$Given \: x^{4}+4\\=\big(x^{2}\big)^{2}+2^{2}$

$We \: know \: that ,\\\boxed {a^{2}+b^{2}=(a+b)^{2}-2ab}$

Here, $\\a = x^{2},\:b = 2$

$=\left(x^{2}+2\right)^{2}-2\times x^{2}\times 2$

$=\left(x^{2}+2\right)^{2}-4\times x^{2}$

$=\left(x^{2}+2\right)^{2}-(2x)^{2}$

$We \: know \: that ,\\\boxed { a^{2}-b^{2}=(a+b)(a-b)}$

$=(x^{2}+2+2x)(x^{2}+2-2x)$

$=(x^{2}+2x+2)(x^{2}-2x+2)$

Therefore,.

$x^{4}+4=(x^{2}+2x+2)(x^{2}-2x+2)$

Let r₁ and r₂be radii of two cyclinder and V₁, V₂be their volume .

Let h be height of the two cyclinders, then

V₁= πr²h and V₂= πr₂²h

∴ V₁/ V_{2 =}πr₁²h / πr₂²h = r₁² / r₂² = 16 / 25 .

Let the ratio be 11x 19x and 24x

11x +19x+24x =540

54x =540 .: x = 540/54

Hence x=10

11x =11×10=110 19x= 19×10 =190

24x=24 × 10 =240
