Question

which of the following values cannot be measured using SI units of length density temperature or all can be measured

Answer 1

The correct answer is "All can be measured".

There are seven SI basic units (the kilogram, the second, the kelvin, the ampere, the mole, the candela, the meter).

So from the given options length can be measured by meter (m^3), for density kilogram per cubic meter(kg/m^3),  and for temperature is kelvins(K).
