Question

A square block of steel with volume 10 cm3 and mass of 75 g is cut precisely in half. The density of the two smaller pieces is now...

Answer 1

a two times the original density.
b one-fourth the original density.
c the same as the original density.

Answer 2

a or b
not really sure

Answer 3

\[\begin{align*} \rho &= \frac{m}{V} \\ \\ &= \frac{\dfrac{1}{2}m}{\dfrac{1}{2}V}\end{align*}\]
Cutting the block in half reduces both the mass and volume of each piece to half of what they were before. The density of the material does not change.

Answer 4

so then its A? @ghuczek

Answer 5

NOT A I MEAN B @ghuczek

Answer 6

No. As I said in my post, the density does not change. That means it has the be the same as it was before.
