We normally think of 3x7, but the "7" is one more than 2 widths ... double the 3 and halve the 7 ==> 6 by 3.5 works ...
Fewer numbers of larger units are required to describe the same volume.
a) If the unit of measure changes from a smaller unit to a larger one, the number of units gets smaller
b) The volume doesn't change.
_____
This should be intuitively obvious to anyone with the experience of puting things into containers of any kind. Fewer large containers are required to hold the same amount of stuff that occupies many smaller containers.
_____
<u>Example</u>
54 ft³ = 2 yd³ . . . . the number of units used to describe the volume changes from 54 to 2. The volume is still 93,312 cubic inches. (Note also that both 54 and 2 are smaller than 93,312.)

i think B i don't know but i only guess
Integers are sometimes split into 3 subsets, Z+, Z- and 0. Z+ is the set of all positive integers (1, 2, 3, ...), while Z- is the set of all negative integers (..., -3, -2, -1). Zero is not included in either of these sets .
