John has a box that is in the shape of a cube (i.
Artemon [7]
A box (cube) has all equal edges or sides (s), thus the volume (v) of the cube is:
v =  {s}^{3} \\ 27 \:  {in}^{3} =  {s}^{3}  \\  \sqrt{( {s}^{3}) } =  \sqrt{( {27in}^3)}  \\ s = 3 \: in
So since each side or edge around is 3 in, then the length around the square bottom of the box = 4×3 = 12 in

Louise begins factoring the polynomial, which has four terms.
ad-work [718]

Louise wants to factorize completely the given polynomial 4x^{3}+12x^{2}+5x+15

Grouping first, second terms together and third, fourth terms together

= 4x^{3}+12x^{2}+5x+15

Taking 4x^{2} common from first and second terms of the given expression and taking 5 common from the third and fourth terms.

==4x^{2}(x+3)+5(x+3)

Taking (x+3) common from the given expression,

==(4x^{2}+5)(x+3) is the completely factored form.
