Answer: From the base unit of length, we can define volume, and from the base units of length, mass, and time, we can define energy. ... ... Since volume is length cubed, its SI derived unit is m3
There are 7 base units, m is one of them. Any unit made up of a combination of them is a derived unit. Also, any unit that is defined to be equivalent to a combination of base units is a derived unit.
