The dimensions of the tank are 50 cm by 32 cm by 20 cm. The tank is full of water and sand. The ratio of the volume of water to the volume of sand is 5 : 1 Work out the number of litres of water in the tank.

Given:

Dimensions of a tank are 50 cm by 32 cm by 20 cm

The tank is full of water and sand

Ratio of volume of water to the volume of sand is 5:1

To find:

Volume of water in the tank in liters

Solution:

Without loss of generality, let,

Length of tank = 50 cm

Breadth of tank = 32 cm

Height of tank = 20 cm

Then, we have,

Total Volume of the tank = Length * Breadth * Height

Total Volume = 50*32*20 cc

Total Volume = 32000 cc

It is given that,

Volume of water : Volume of sand = 5:1

(Volume of water)/(Volume of sand) = 5/1

Cross multiplying, we have,

Volume of sand = (Volume of water)/5

It is also given that the tank is full of water and sand. This implies that,

Volume of water + Volume of sand = Total Volume

Using the value, we obtained, we get,

Volume of water + (Volume of water)/5 = Total Volume

(6 * Volume of water)/5 = Total Volume

Plugging in the value of total volume, we get,

(6 * Volume of water)/5 = 32000 cc

Volume of water = cc

Volume of water 26,666.6667 cc

We know that,

1 cc = 0.001 liters

26,666.6667 cc = (26666.6667 * 0.001) liters

26,666.6667 cc 26.667 liters

Thus, Volume of water in the tank is approximately 26.667 liters

Final

Volume of water in the tank (in liters) is approximately 26.667 liters

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
