## What is the easiest way to find the cube of a matrix?

Take the matrix 𝐴 equals one, zero, zero, zero, five, zero, zero, zero, two. Then, what we need to do is find 𝐴 squared and then use this to find 𝐴 cubed.

**How do you calculate the squares of a house?**

Measure the length and width, in feet, of each room. Multiply the length by the width and write the total square footage of each room in the corresponding space on the home sketch. Example: If a bedroom is 12 feet by 20 feet, the total square footage is 240 square feet (12 x 20 = 240).

### How do you calculate cube?

Mathematically, calculating volume using the cube dimensions formula uses the standard formula of length times width times height, or LxWxH. Since all sides of a cube have the same length, the calculation for cubes becomes length cubed, or L3.

**How do I calculate the square and cube of a matrix?**

As per my knowledge there is no shortcut method for calculating square and cube of matrix. You have do all multiplication and sums. But if you are calculating more than three you can calculate like recursive method. e.g. for A^4 = (A^2)* (A^2) = ( ( (A*A)*A)*A) And If you want more faster use Matlab or Octave :-).

#### How do you find the first row of the Cube 13?

Find the cube of 13. Step 1: Note down the cube of the tens place that is 1. And also the geometric ratio between 1 and 3 is 1:3. Therefore the first row is 1 3 9 27 Step 2: Note down the 2 times of second and third number that is 6 and 18. Step 3: Now adding the rows will give the answer.

**What is the cube root of a number?**

The cube root of a number is … a special value that when cubed gives the original number. This is the special symbol that means “cube root”, it is the “radical” symbol (used for square roots) with a little three to mean cube root.

## How many squares are there in a m x M matrix?

Input: m = 4, n = 3 Output: 20 There are 12 squares of size 1×1 + 6 squares of size 2×2 + 2 squares of size 3×3. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution. From above explanation, we know that number of squares in a m x m matrix is m (m+1) (2m+1)/6
