Maths is a subject where we learn theories, logics and different types of formulas. Have you ever thought about how these formulas and concepts are useful in everyday life? Why we have to learn and practice problems based on them? Or what is the need of solving linear equations? Let us discuss here some of the key formulas which are used in real-life scenarios to get the answers to all these questions.
Suppose you have to reach a place at 9 o’clock in the morning which is 90kms from your home and you have left only at 7.30 am. If you are going there by car, then it is required to know at how much speed you need to drive the car to reach there on time. This is possible by using the formula for speed which is equal to the ratio of distance and time.
The volume is the space occupied by a three-dimensional shape or object. At home, we have many objects like jars, food container, buckets, etc. which are used to store food or water. All these objects have their own capacity to carry any solid or liquid products. These containers could be of any shape such as cylindrical or cube shape. Hence, their formulas for volume also differ from each other.
Similar to volume another property of any geometrical shape is its area. Area is the region covered by the outer surface of an object in a plane. You will come across formulas for area of sphere, area of rectangle, area of cone, etc. in mensuration topic. For an example, if we have to place a wooden box in a room, then it’s surface area will help us to judge how much space it will be required by the box in the room.
Profit and Loss
In business, we usually use the formulas to calculate the percentage of profit and loss, such as:
Profit = Selling Price – Cost Price
Loss = Cost Price – Selling Price
These formulas help a salesperson to check how did the business go in a day or month.
In the same way, there are many formulas in Mathematics, which are used to calculate certain quantities. That is why it is necessary for us to remember at least the basic formulas which are used frequently in day-to-day life.
