A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm, which quadratic equation best models the volume of the box?
V = lwn
P = 2(1 + w)
y = 5(28 - x)(x)
y = 5(28 - 2x)(x)
y = 5(14 - x)(x)
y = 5(14 - 2x)(x)

Step-by-step explanation:

Given: Height of the box is 5 cm

The rectangular base of the box has perimeter of 28 cm.

To find: Volume of the box

Solution:

Let l, b, h denote length, breadth and height of the box.

Let

Perimeter of the rectangular base of the box =

Therefore,

Volume of box =
