Yasmin is wrapping a box in the shape of a cube with a side length of (2x-3)

A. What is the surface area of the box?

B. What is the volume of the box

Given:

Each side of the cube shaped box =

To find the surface area of the box and the volume of the box.

Formula

If the each side of cube is a,

Now,

Putting we get,

The surface area, sq unit

sq unit

sq unit

And,

The volume, cube unit

cube unit

Hence,

The surface area of the box is sq unit and

The volume of the box is cube unit.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
