RRB NTPC 2025 Under Graduate CBT 1 Question Paper PDF (20-Jun-2026) (Shift 3)
The correct answer is

Kilogram per metre cubed

Density, defined as mass per unit volume, is correctly represented in SI base units as kilogram per metre cubed.

Gram per litre, kilogram per litre and milligram per cubic centimetre use non-SI base units, not the correct SI combination for density.

Hence, 'Kilogram per metre cubed' is the correct answer.
