The formula to work it out is Pi x Radius2. The rest is up to you !
Cubic inches measures volume. Square inches measures area. Therefore, you can not compare the two. It is like comparing feet and cups.
It is: 7*7 = 49 square inches
A square with a side length of 6 inches has an area of 36 square inches.
There is no such thing as a square whose length and width are different.

The question makes no sense. Square feet measures area. Inches measures length. There are, however, 7.76 square feet in in 1118 square inches. (Divide by 12x12.)
Assuming it is a circular mirror, let the radius of the mirror be R inches. Then the combined radius is R + 3 inches → Combined area is π × (R + 3)² square inches. [If you know the radius of the mirror, substitute its value for R in the above formula and you will get the area in square inches. If the mirror is another shape, you'll have to reask your question with more information.]
The area is 144 square inches.
It is: 7*7 = 49 square inches
4 inches x 4 inches = 16 square inches
A square foot measures 12 inches by 12 inches - which equals 144 square inches. That means that 1152 square inches = 1152/144 = 8 square feet.
A square with a side length of 6 inches has an area of 36 square inches.
238.6 square feet.
There is no such thing as a square whose length and width are different.

It is: 2 times 3 = 6 square inches
