volume is length times width times height
v=l x w x h
Ohm's Law states that Voltage = Current x Resistance. This is true, but not the answer to the question. The mathematical expression is simple but misleading in its simplicity: Vsource=...
a numeral.
Volume is the amount of 3-dimensional space occupied by an object
Generally it is the area of the base times the height. Go to the website I linked for specific formulas.
V = B x W x H or Volume = Base x Width x Height
