A block of aluminum has a mass of 39.589 g and measures 5.10 cm by 2.50 cm by 1.15 cm.What is the density of the rectangular aluminum block?

Question

Quizplus · Accepted Answer

The density of an object is calculated by dividing its mass by its volume. The volume of the rectangular block is found by multiplying its length, width, and height: $5.10 \, \text{cm} \times 2.50 \, \text{cm} \times 1.15 \, \text{cm} = 14.6375 \, \text{cm}^3$. The mass of the block is $39.589 \, \text{g}$. Therefore, the density is $39.589 \, \text{g} / 14.6375 \, \text{cm}^3 = 2.70 \, \text{g/cm}^3$.
