Question

11.	You are given a block that has a mass of 3.42 grams. You measure it’s volume to be 2.00 cm by 5.00 cm by 4.00 cm. Calculate the density of the block.

jdoe0001 · Answer

density will be $\bf \cfrac{weight}{volume}  \implies \cfrac{3.42gms}{2cm\times 5cm \times 4cm}$

anonymous · Answer

ok solve that equation thing right ok thank you

anonymous · Answer

so 0.0855 would be correct, checking with u.

anonymous · Answer

what would be the unit?

jdoe0001 · Answer

well, what do you think will be the unit?  notice the fractions, they have their units :)

anonymous · Answer

lol tell me this is for test review that i already finished the test, so its worthless, but its required to turn in, i got 35/35 on my test btw

jdoe0001 · Answer

$\bf \cfrac{weight}{volume}  \implies \cfrac{3.42gms}{2cm\times 5cm \times 4cm} \implies \large 0.0855 \frac{grams}{cm^3}$


so, that means, that, there are 0.0855 grams per each cubic centimeter

anonymous · Answer

oh ok thank you :D

jdoe0001 · Answer

yw

anonymous · Answer

wait

anonymous · Answer

gms^3 is that right? lol

jdoe0001 · Answer

$\bf cm \times cm \times cm \implies cm^3$

anonymous · Answer

so no grams, just cm^3 so 0.0855cm^3?

jdoe0001 · Answer

$\bf \cfrac{weight}{volume}  \implies \cfrac{3.42gms}{2cm\times 5cm \times 4cm} \implies \large 0.0855 \color{red}{\frac{grams}{cm^3}}$
