Hint: As the given units square inches and square foot are units of measurement. So we need to find the relation between the two to get the desired answer. Then we will discuss how we can convert the units.

Complete step-by-step solution:
We have to find out how many square inches are in a square foot.
As we know that measurement is the obligation of a member to characteristics of an object which can be compared with other objects. A unit of measurement is a definite magnitude of the quantity defined by convention law that is used as a standard of measurement of the same kind of quantity. We have two kinds of units of measurement as square inches and square feet. As foot is the singular form of feet and it can be written as ft. (an abbreviation and IEEE standard symbol).
Now, we know that 1 foot = 12 inches. But here we have been asked the square of the unit so on doing square both side we get 1 square feet = (12)2 =144 square inch
So we have 144 square inches in a square foot.

Note: Square foot is an imperial unit mainly used to represent area. The common mistake students can make that they may confuse while converting the units whether to multiply or divide. While conversion of greater unit into smaller we have to perform multiply, converting the smaller unit to a larger one we have to divide.
