What is the density of a 42.0 gram cube with a length of 5.0 cm, a width of 3.0cm, and height of 7.0cm

0.4g per 1 cm3

Explanation:

5.0 × 3.0 × 7.0 = 105 cm3 this is the volume of cube

density is mass per unit of volume

d = m / V then 42g / 105 cm3 = 0.4 g/ 1 cm3

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
