Answer:
[tex]\boxed {\tt \frac{2}{3} \ or \ 0.666666667 \ g/cm^3}[/tex]
Explanation:
Density can be found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass is 20 grams.
We have to find the volume.
- To find the volume, multiply the length by the width by the height.
- V= l*w*h
- l= 2 cm, w= 5 cm, h= 3 cm
- V= 2 cm * 5 cm * 3 cm = 30 cm³
[tex]m= 20 \ g\\v= 30 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac{20 \ g}{30 \ cm^3}[/tex]
Divide.
[tex]d=\frac{2}{3} \ g/cm^3[/tex]
[tex]d= 0.666666667 \ g/cm^3[/tex]
The density is 2/3 grams per cubic centimeter.
