yes always
no.. VOLUME is the amount of space occupied by a three-dimensional object or region of space, expressed in cubic units while area, measure of the size of a surface region, usually expressed in units that are the square of linear units, e.g., square feet or square meters.
The surface area of a shape is expressed in square units.
Gold nuggets (Or anything that exists, for that matter) are in the third dimension. They have length, width, and height. For two dimensional objects, the area is expressed in square units, but because the gold nugget is in the third dimension, it's volume is expressed in cubic units.
The length of a triangle can't be expressed in square units and only its area is expressed in square units
Because it is the square units around the base.

36 square units. You can't express a perimeter in square units; a perimeter is a length expressed in ordinary units. If the perimeter of this square is 24 units then the answer above is correct.
The volume of solid objects is commonly expressed in cubic units, such as cubic centimeters (cm³) or cubic meters (m³). This quantifies the amount of space the object occupies.
Mass is expressed in grams in the SI system and slugs in the English system. (these are the base units obviously multiples of these units exist. ex: kg). Volume is expressed as a cubic of any unit of length ex: M^3.
It is the volume!
