6. what is the mass of the block of iron illustrated below? hint: calculate the volume of the block first. next look up the density of the block in the table above. finally, flip the density formula to solve for mass. v = l x w x h 2 cm 10 cm 5 cm
Answer
Explanation:
Step1: Calculate volume
$V = L\times W\times H=10\times5\times2 = 100\ cm^{3}$
Step2: Assume density of iron
The density of iron is approximately $\rho = 7.87\ g/cm^{3}$ (a common - known value).
Step3: Solve for mass using density formula
The density formula is $\rho=\frac{m}{V}$, so $m=\rho\times V$. Substituting the values, we get $m = 7.87\times100=787\ g$.
Answer:
$787\ g$
