The dimensions in inches of a shipping box can be expressed as width x, length x + 1, and height x - 4. the volume is 84 ft^3. find the dimensions of the box in feet.

1, 1, 4
2, 2, 21
2, 6, 7
3, 4, 7

? if somebody can put this into an equation for me, i can do the rest.

The dimensions of the box are

Step-by-step explanation:

we know that

The volume of a box in the shape of a cube is equal to

where

W is the width of the box

L is the length of the box

H is the height of the box

In this problem we have

Substitute the values in the formula of volume

Using a graphing tool

Solve the cubic function

see the attached figure

The value of x is equal to

the dimensions of the box are

no this is a nonlinear negative

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
