Answer 1

Question :

A milk container is 8cm long and 50 cm wide what should be its height so that it can hold a litre of milk.

Answer :

The height of the milk container is 2.5 cm.

Step-by-step explanation :

Given,

Length of container, $l=8$ cm

Breadth of container, $b=50$ cm

The container can hold one litre of milk = 1000 cm²

To find the height of the milk container.

Volume of cuboid -

⇒ lbh

⇒ 1000 = 8 × 50 × h

⇒ h = 1000 / 400

⇒ 2.5 cm

Answer 2

Answer:

2.5 cm

Step-by-step explanation:

Length of milk container $l$ = 8 cm

Breadth of milk container $b$ = 50 cm

Now, 1 litre = 1000 cm³

Volume of milk container = 1000 cm³

Let the height $(h)$ be $h$.

Volume of container = 1000 cm³

⇒ $l \times b \times h$ = 1000

⇒ 8 × 50 × $h$ = 1000

⇒ 400 × $h$ = 1000

⇒ $h$ = 1000 / 400

⇒ $h$ = 2.5 cm

Hence, the height of milk container should be 2.5 cm.
