A block on your desk acts as a paperweight with measurements of 3 cm by 4 cm by 6 cm. The block has a mass of 184.32 g. What is its density?
Correct answer
B
Rationale
Density is calculated by dividing mass by volume. To find the volume of the block, multiply its dimensions (3 cm x 4 cm x 6 cm = 72 cm?é??). Dividing the mass (184.32 g) by the volume (72 cm?é??) gives a density of 2.56 g/cm?é??. Therefore, the correct answer is B.
