Answer:

Length , Breadth & Height = 1 , 2 , 3

Step-by-step explanation:

Length , Breadth & Height of a cuboid is given by

x³ - 6x² + 11x - 6

so we need to find the three roots of given equation to find

Length , Breadth & Height

x³ - 6x² + 11x  - 6 = 0

just by seeing we can see that x = 1 satisfies this

=> x - 1 is a factor of this

x³ - x² - 5x² + 5x + 6x - 6 = 0

=> x²(x - 1) - 5x(x - 1) + 6(x - 1) =0

=> (x-1)(x² - 5x + 6) = 0

=> (x -1)(x² - 2x - 3x + 6) = 0

=> (x -1)(x-2)(x-3) = 0

=> roots are 1 , 2, 3

Hence Length , Breadth & Height = 1 , 2 , 3

The length breadth the height of a Cuboid of her project is (x -1), (x-2), (x-3).

Step-by-step explanation:

Consider the information,

The provided polynomial x^3-6x^2+11x-6

The polynomial represents the volume of the cuboid.

V=lbh

Factor the polynomial as shown below:

Substitute x = 1 in above polynomial.

1^3-6+11-6=0

x-1 is a factor of the polynomial so divide the provided polynomial by x-1.

\frac{x^3-6x^2+11x-6}{x-1}=x^2-5x+6

Now factor out x^2-5x+6

x^2-5x+6=x^2-2x-3x+6\\=x\left(x-2\right)-3\left(x-2\right)\\=(x-3)(x-2)

Hence, the length breadth the height of a Cuboid of her project is (x -1), (x-2), (x-3).
