6a. Suppose you need to find a box that you can fit your cube-shaped gift into. You know that you will need to find a box that is 4 inches longer than the cube's length, 3 inches wider than the cube's width, and 7 inches taller than the cube's height. Create a polynomial that represents the gift box's volume in terms of the cube's length/width/height, in factored and standard form

Rivera · Answer 1

V = (x + 4) (x + 3) (x + 7); V = x³ + 14x² + 61x + 84

Step-by-step explanation:

Let x = the side of the cube

Then the dimensions of the gift box are

l = x + 4

w = x + 3

h = x + 7

V = lwh

V = (x + 4) (x + 3) (x + 7) Multiply the first two terms

V = (x² + 7x + 12) (x + 7) Remove parentheses

V = x³ + 14x² + 61x + 84

Carlo Vazquez · Answer 2

(l + 4) * (w + 3) * (h + 7)

let l represent the length, w represent the width, and h represent the height of your cub-shaped gift.

Though, if your gift is in the shape of a cube, that would mean all the sides are the same length.

(2 + 4) * (2 + 3) * (2 + 7)

6 * 5 * 9 = 270

(I haven't done geometry in awhile though, so this may be incorrect unless it actually makes sense.)
