<h3>What is unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value
Given:
height of 1 crate = 3 feet
height of 1 crate in inch = 3*12
= 36 feet
Hence, the height of stack of shipping crates is 36 feet.
