The area ratio is 1:16 meaning that the old area is 1 while the new area is 16. So this is another way of saying "the area is multiplied by 16"

Take the square root of each part of the ratio of 1:16 and we get 1:4

So this is the scale factor. It tells us how the linear components of the circles relate to one another. If the circumference of the smaller circle is 1,then the larger circle has a circumference of 4.

Therefore, the circumference has been multiplied by 4

OLEGan [10]
<h2>Answer:</h2>

The height of the box is:

                             4 ft.

<h2>Step-by-step explanation:</h2>

Let "h" denotes the height of the box.

Length of box is denoted by "l"

and breadth or width of box is denoted by "b"

We are given l=18 ft

b=8 ft.

Also we are given surface area of rectangular box= 496 ft²

As we know that the surface area of box is given by:

Surface\ Area=2(lb+bh+hl)

i.e.

496=2(18h+8h+144)\\\\i.e.\\\\\\496=2(26h+144)

Divide both side by 2.

248=144+26h\\\\i.e.\\\\26h=248-144\\\\i.e.\\\\26h=104

on dividing both side by 26 we get:

h=4

     Hence, the height of the  box is:

                    4 ft.
