No. A cube with sides which are 1 centimetre long or that of 1 inch are both unit cubes, as is a cube with sides of 1 decimetre (volume = 1 litre).

Assuming you are using the same unit of measurement for the cubes and the boxes, you can fit 125 cubes in the box.
Depends on the size of the brick! If they are 1 unit cubes, then 4 rows of 16

you do not, one is a unit of measure, the other is a shape.
The answer depends on the exact size of the solid figure.
The answer probably is 3*2*4 = 24 unit cubes but you could also do it with 10 cubes: 2 cubes of size 2*2*2 and 8 unit cubes. The question does not require the cubes to be unit cubes.

No, because not all toothpicks are the same size. However, one single toothpick could be used as long as you always used the same one.
A cube with an edge length of 6 units has a 216 square unit surface area and a 216 cubic unit volume.
Units of density are mass per unit volume. Unit volume might be a cubic centimeter or a cubic foot, for example. Whatever the size of your sample, a cubic foot of it is always a cubic foot, and the mass of that cubic foot will always be the same.
A unit in mathematics is the measurement of an object, such as cubes. EXAMPLE: 1 cube is one unit.
