If a match box of size 5 cm × 4 cm × 1 cm is filled with nuclear matter, what will be its expected mass? The density of the nuclear matter is approximately $2.3×10^{17} kg\, m^{−3}$.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $4.6×10^{12} kg$
Mass = Density × Volume
⇒ Mass = $(2.3×10^{17})×(2×10^{-5})$
$=4.6×10^{12} kg$
