2.
can it hold? (1 m= 1000 I)
3. A cuboidal vessel is 10 m long and 8 m wide. How high must it be made to hold 380
cubic metres of a liquid?

Answer 1

Answer:

Sol: Here, Length (l) = 6 m

Breadth (b) = 5 m

Depth (h) = 4.5 m

Capacity = l × b × h = 6 × 5 × 4.5 m3

∵1 m3 can hold 1000 l.

∴135 m3 can hold (135 × 1000 l = 135000 l) of water.

∴ The required amount of water in the tank = 135000 l.

3rd Answer :

Sol: Length (l) = 10 m

Breadth (b) = 8 m

Volume (v) = 380 m3

Let height of the cuboid be 'h'.

Since, volume of a cuboid = 1 × b × h

∴ Volume of the cuboidal vessel = 10 × 8 × h m3 = 80h m3

⇒ 80h = 380

Thus, the required height of the liquid = 4.75 m

Answer 2

Answer:

Water tank can hold water equal to its volume. So, the water tank can hold 135000 litres of water.

Step-by-step explanation:

Answer. Therefore,the vessel must be made to a height of 4.75 m to hold 380 cubic meters of a liquid
