Answer 1

Answer:

770 liters = 770000 cm3 = width x depth x length

Length = 770000 cm3 /(110cm x 70cm) = 100cm

Step-by-step explanation:

Answer 2

Final Answer:

The length of the rectangular tank, which isis 110cm wide and 70cm deep and can contain 770 liters of water is 100cm.

is 100cm.

Given:

A rectangular tank is 110cm wide and 70cm deep.

It can contain 770 liters of water.

To Find:

The length of the tank

Explanation:

The following conversion is important for solving the problem.

There is one thousand cubic cm in one litre of volume.

Step 1 of 2

Assume that the length of the rectangular tank is x cm.

From the first statement here, the following is the volume of the tank in cubic cm.

$V\\=110\times 70\times x\\=7700x$

Step 2 of 2

In line with the second statement of the problem, the volume of the tank in litres is 770, which is equivalent to 770,000 cubic cm.

Now, the following equation can be written and solved.

$7700x=770000\\x=770000\div7700\\x=100\;cm$

Therefore, the required length of the tank is 100 cm.
