Select ALL the fundamental quantities listed in the material.

### Why this is right - **Length** is a base quantity used to describe distance or size. - **Time** is a base quantity used to describe duration. - **Mass** is a base quantity describing the amount of matter in an object. ### The concept Fundamental quantities are independent starting points for measurement systems. Derived quantities are made from them: area uses length squared, and speed uses distance divided by time. This is why area and speed are not fundamental, even though both are common measurements. ### The other options - **B. Area**: area is derived from length multiplied by length. - **D. Speed**: speed is derived from distance divided by time. ### Terms - **Length**: a base measurement of distance or size. - **Time**: a base measurement of duration. - **Mass**: a base measurement of the amount of matter. - **Area**: a derived measure of surface size. - **Speed**: distance travelled per unit of time. ### Remember Length, time, and mass are base quantities; area and speed are built from base quantities.
