## What is magic numbers in chemistry?

The concept of magic numbers in the field of chemistry refers to a specific property (such as stability) for only certain representatives among a distribution of structures. It was first recognized by inspecting the intensity of mass-spectrometric signals of rare gas cluster ions.

## How do you calculate area?

To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.

## How do you work out the square meter of a triangle?

To calculate how many square metres for a triangle multiply the length x width and divide by two.

## How do you calculate volume?

To find the volume of a box, simply multiply length, width, and height — and you’re good to go! For example, if a box is 5×7×2 cm, then the volume of a box is 70 cubic centimeters.

## How do you use scientific notation in mastering physics?

Mastering does not support E notation. To include a large or small number in your answer to a Mastering question, use the provided Equation Editor menus or keyboard shortcuts to enter the number in scientific notation.

## How 1729 is a magic number?

It is 1729. Discovered by mathemagician Srinivas Ramanujan, 1729 is said to be the magic number because it is the sole number which can be expressed as the sum of the cubes of two different sets of numbers. Ramanujanâ€™s conclusions are summed up as under: 1) 10 3 + 9 3 = 1729 and 2) 12 3 + 1 3 = 1729.

## IS 12 is a magic number?

## How do you find the area of 4 unequal sides?

Use the formula below: Area = (Side 1 × Side 2) × sin (angle) or A = (s1 × s2) × sin(θ) (where θ is the angle between sides 1 and 2). Example: You have a kite with two sides of length 6 feet and two sides of length 4 feet. The angle between them is about 120 degrees.

## How do you find area with 3 sides?

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it.

## What is volume of square?

The volume of a square box is equal to the cube of the length of the side of the square box. The formula for the volume is V = s3, where “s” is the length of the side of the square box.

## What are 3 ways to calculate volume?

1. Solve for Volume by Space. All physical objects occupy space, and you can find the volume for some of them by measuring their physical dimensions.
2. Solve for Volume by Density and Mass. Density is defined as an object’s mass per a given unit of volume.
3. Solve for Volume by Displacement.
