44. How many bricks, each measuring 30 cm x 20 cm 5 cm will be needed to construct a wall 10 m lon 6 m high and 12 cm thick? |
|
Answer» The dimensions of Brick = 30 cm, 20 cm, and 5 cm. The dimensions of Wall = 10 m, 6 m, and 12 cm. To find : how many bricks are needed to construct the wall? SOLUTION : ⇒ Let's find the VOLUME of the Brick. The volume of the brick = l × b × h = 30 × 20 × 5 = 30 × 100 = 3000 cm³ ⇒ Let's find the Volume of the Wall. Here, before finding the Volume, we have to convert the length and breadth from cm to m.→ 10 m to cm.1 m = 100 cm 10 m = 10 × 100= 1000 cm→ 6m to cm.1 m = 100 cm 6 m = 6 × 100= 600 cm The volume of the wall = l × b × h = 1000 × 600 × 12 = 600000 × 12 = 7200000 cm³ ⇒ Now, let's find how many bricks are needed. No of bricks = Volume of Wall/Volume of Brick = 7200000/3000= 2400Therefore, 2400 bricks are REQUIRED to construct a wall. |

A pizza is divided into equal slices as shown. What part of the pizza below would remain if you ate two of the slices? |
|
Answer» s a country full of peace, colours, cultures, languages, people, plants and animals etc. India is also god's own country, where we have a holy PLACE, river and temple etc. This makes us proud Indians.I am lucky to born in India, which is an independent country and where we have all the facilities. Even it has the freedom to do everything. So, why we can't use our freedom to CONTRIBUTE our own nation? Still, India has given us everything.All the people staying in India contribute to India by paying TAXES which is compulsory for all, for rich as well as poor. But is this a real contribution?I hope you all will know that the British ruled India before the INDEPENDENCE of our country. They never treated Indians equally. And now after the Independence of our country, we the Indians never treated others equally. So what is the use of Independence of our country?We should HELP the senior citizens, as they are a part of our country.We should provide food, medical and education service, who can't afford to do that.Even plants and animals are part of our country. So, we should help and protect them before they get extinct.We should stop global warming, to get fresh air and good surroundings. We can't stop global warming but we can reduce it by using public transport because it reduces fuel to burn and saves our money too. We can also follow R's - Reduce, Recycle, Reuse.Even there are more other things which can lead to the development and contribution of our nation too. I hope you all may be experienced it that, "People may doubt what you say; but they will believe, what you do". So, we the Indians promise to be united and do our work for our nation. Then only we can proudly say, "JAI HIND". |
