Apacking box has the dimensions 3 by 2 by 5 1/2
what is the volume of the box?
feet.

The volume of packing box is 33 unit³

Step-by-step explanation:

Given as :

The dimension of packing box  are 3 by 2 by 5

I.e Length = 3 unit

   Width = 2 unit

   Height = 5  = 5 + = unit

Let the volume of box  = V unit³

∵ The shape of box is similar to the shape of cuboid

So,  volume of box = Length × width × Height

Or, V  = 3 unit × 2 unit ×   unit

∴    V = 3 × 11 = 33 unit³

Hence The volume of packing box is 33 unit³  Answer

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
