Question

1. 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

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 $
ho = 7.87\ g/cm^{3}$ (a common - known value).

Step3: Solve for mass using density formula

The density formula is $
ho=\frac{m}{V}$, so $m=
ho\times V$. Substituting the values, we get $m = 7.87\times100=787\ g$.

Answer:

$787\ g$
