CASE STUDY - I, WATER TANK, Water is one of most commonly used substances on our Earth. We need water for all activities in our, day to day life. Water supply in urban areas is always short against the real demand. Due to rapid, urbanisation, infiltration of rain water into subsoil has decreased and recharging of ground water, has diminished. This scenario requires an alternative source to bridge the gap between demand and, supply. Rainwater which is the purest form of water and easily available would be an immediate, source to augment the existing water supply. Neelkanth society, Pune has also installed one cubical, tank to store rainwater using roof top., 200 m, Cubical tank, 18. Calculate the total surface area of cubical tank?, 19. How much quantity of water can be collected in cubical tank?, 20. What will be the lateral surface area of cubical tank?, 21. What will be cost of painting cubical tank if the box painted at the rate of 15 per 100 m²,, Leaving upper and lower base?, 22. If we join three cubes adjacently, we will get a

CASE STUDY-II, DART GAME, Darts is a precision game that tests your accuracy and technique. The game involves throwing darts, at a target board with a level of precision that will help you score better than your opponents. Three, children were playing dart game to improve their concentration and threw dart on target board with, radius 10 cm and centre O. Darts land on target board at positions A, B and C respectively. They, drew lines to join AB, BC and CA and got a triangle shaped figure such that AC = BC., A, B, Now, answer the following questions, 23. What type of triangle is ABC?, 24. What is the length of AOB?, 25. What is the measure of ZCAB?, 26. What is the measure of major arc BAC?, 27. AC is a

Find the value of x., CASE STUDY - II, PARTY BIRTHDAY, Reema was very excited about her birthday as only two days were left for her birthday, party. She was telling her tuition teacher about her birthday party and also shown the, things purchased by her for the birthday party such as candles, sweets, caps, cold drinks, cans, fruit juices bottles etc. Her tuition teacher asked Reema to bring caps and cylindrical, containers which they have purchased as she was teaching her "Mensuration Topic"., They observed the cylindrical container has 220 cm circumference and 14 cm height., Conical cap has radius of 15 cm and vertical height 20 cm., On the basis of above information, answer the following questions:, 23. What is the radius of cylinder?, 24. How much fruit juice can be filled in cylinder?, 25. What will be the slant height of cap?, 26. Find out the C.S.A of conical cap., 27. What will be the total outer S.A of cap?

There is severe crisis of employment opportunities in real, Case Study- I, CLASS TEST, oar lockdown due to COVID-19, Pandemic a study came which has shown that in Lucknow, the, labour market. An NGO “Meal for All" is helping the, cople in this difficult time. They have designed cuboidal, hoxes and kept them in different residential societies, People can put things such as medicines pulses, flour, oil, etc, in packets. These boxes are then taken to different, slum areas nearby for distribution., On the basis of above information, answer the following, 10 m, 5 m, 15 m, questions:, 18. What will be lateral surface area of cuboid?, 19. After collecting things, cuboidal box is to be packed with the sheets of paper. How much, sheets of paper is required to cover one cuboidal box?, 20. Boxes are to be sent in different slums so, volunteers have decided to label them. Diagonally, with one white strip and write the name of locality. What will be length of tape required to, cover one box?, 21. What will be the cost of sheets of paper in 5 boxes, if cost per 100 m2 is 7?, 22. Find the volume of cuboidal box., Case Study- II, PAPER FOLDING, Teaching Mathematics includes wonder of patterns, shapes, visual points and possibilities that could, be explored in classrooms but most fascinating has been the use of paper folding. It enthusiases,, calms, inspires and delights teachers and pupils both. Mrs Anupama was explaining same concept, of circles in classroom when she drew the following figure and labelled the figure. She told them, that OA = 5 cm, AB = 8 cm and OC 1AB., 5 cm, B, -8 cm
