Question

One dozen means how many items? One gross means how many items?

Answer 1

Hint: We first explain the term dozen and then using the 1 gross being equal to 12 grosses, we find the value of 1 gross. The multiplication of 12 to 12 gives 1 gross being equal to 144. We also express it in the form of an exponent.

Complete step by step answer:
We first explain the terms dozen and gross.One dozen means a collection or a set of 12 items of the same thing, like 12 screws or 12 apples. Dozen, the unit of measurement, started in primitive days where it was used to group a set of twelve items, which is still followed.
One gross means a dozen of dozen things, or a square of a dozen.
We get $12\times 12=144$ is equal to one gross. So, it is equal to ${12}^2$.
The word ‘gross’ refers to numbers that are multiples of exponents of twelve.

Note: Number 12 was fixed following the number of months in a year or a solar cycle or the 12 cycles of the moon. Gross is also further classified as great gross (a group of 1728 items) and small gross (120 items).
