Answer:
50.6368 g
Step-by-step explanation:
*Note that the equation p = m/v
p is the density. m is the mass. v is the volume.
1. First find the volume of the foam block:
(length) x (width) x (height) = volume
4.3 cm x 3.2 cm x 1.6 cm = 22.016
2. Set up the equation:
If your foam block has a density of 2.3 g/cm and a volume of 22.016 cm. Put these numbers both into the equation. I am going to use m to represent the mass.
2.3 g/(cm) = m/ 22.016(cm)
2.3 x 22.016 = m
50.6368 = m
So, your mass is 50.6368 g
Last year I took an engineering class, and while I don't remember every detail that was taught, I do remember the teacher explaining the mass isn't the same as weight. Since in the question gravity isn't mentioned I am assuming that they want the mass, if that is not the case...
Weight= mass * (the force of gravity)
So you would take the gravity force (if you were provided with one) and multiply that by 50.6368g
