Question

the shape of a water tank is mounted on lorry is cylinder with 2 hemisphere stuck to each of its ends.the uniform thickness of a tank is 7cm the total length of the tank is 700cm and diameter is 56cm the tank is full of water the entire water filled in water containers if the capacity of each containers is 672cm.cube find the required number of containers

Answer 1

shape of container is not mentioned
I took shape of container as cylinder
number of containers can be filled= 1744(approx)

Answer 2

Answer:

Number of Required Container is 4859.

Step-by-step explanation:

Given:

Length of the water tank = 700 cm

Diameter of the water tank = 56 cm

Radius of the water tank , r = 28 cm

Shape of the water tank = 2 hemisphere in both ends of the cylinder.

Volume of the Water tank = volume of cylinder + 2 × Volume of the Hemisphere.

Volume of the Water tank = $2\pi r^2h+2\times\frac{2}{3}\pi r^3$

height of cylinder, h = total height - 2 × radius = 700 - 28 - 28 = 644 cm

Volume of the Water tank = $2\times\frac{22}{7}\times(28)^2\times644+2\times\frac{2}{3}\times\frac{22}{7}\times(28)^3$

= $2\times22\times28\times4\times644+2\times\frac{2}{3}\times22\times(28)^2\times4$

= $2\times22\times28\times4\times644+2\times\frac{2}{3}\times22\times(28)^2\times4$

= 3173632 + 275968 /3

= 9796864 /3 cm³

Number of containers with 672 cm³ = (9796864/3)/672 = 43736/9 ≈  4859

Therefore, Number of Required Container is 4859.
