Question

Change $396$ inches into feet.

Answer 1

Hint: This question belongs to the unit conversion topic, that is we have to convert the unit from one form to another. We have to convert the unit inches to the unit feets. In the question, we have to find what number of feet corresponds to $396$ inches.

Complete step by step solution:
The inches and feet are the units to measure the length of physical commodities or items. An inch is abbreviated as in and feet is abbreviated as ft. An inch is a unit of length and it is used for measuring small lengths. Feet is also a unit of length and is used for measuring lengths of comparatively longer objects.
The given question requires us to convert the units of length. We have to convert $396$ inches into feet.
We know that each feet of length consists of $12$ inches. So, $12$ inches of length is equivalent to one foot.
Let the number of feet that correspond to $396$ inches be x.
Then, to convert $396$ inches into feet, we follow the unitary method where we first find that how many units of milliliters correspond to a single unit of inch and then multiply both sides of the equation by a suitable number so as to get the desired conversion of $396$ inches.
So, $1$ feet \[ = 12\] inches
Dividing both sides by twelve, we get,
$ \Rightarrow 1\,inch = \dfrac{1}{{12}}feet$
Now, multiplying both sides by $396$, we get,
$ \Rightarrow 396\,\,inches = 396 \times \dfrac{1}{{12}}feet$
Cancelling common factors in numerator and denominator, we get,
$ \Rightarrow 396\,\,inches = 33\,feets$
Hence, $396$ inches is equivalent to $33$ feets.

Note:
We have different units for solid quantity, liquid quantity and gaseous quantity. Every quantity has a measurement unit from the low quantity to the high quantity. While converting the unit of a quantity from one form to another form we have a standard value. By multiplying or dividing we can convert the unit of the quantity. We have a different system of measurement of a quantity.
