Answer:
12,000,000 boxes
Explanation:
the volume of the room can be found by using the equation for volume of a rectangular box:V=LxWxH
where:
L=2m
W=3m
H=4m
(it doesn't really matter which is which since it is multiplication)
when we multiply our values (2m*3m*4m) we get 24cubic meters
now we need to convert cubic meters to cubic centimeters
each cubic meter is 1,000,000 cubic centimeter we multiply 24 by 1,000,000 and we get: 24,000,000 cubic centimeters (cc)
dividing 24,000,000 by 2 (since each box is 2cc) we get 12,000,000
so, we know we can fit 12,000,000, 2 cubic centimeter boxes in this room
Acids are danger so stay away
Particle-A is an electron, racing around in a cloud that's far from the nucleus.
Particle-B is either a proton or a neutron, in the nucleus.
The big clue is where you said that particle-A has very little mass
compared to particle-B. Protons and neutrons have almost identical
masses, but it's the same mass as more than 1,800 electrons !
30*3*60=5400
300*2=600
1500*3=4500
200*10*60=120000
the computer uses more energy.
(you can multiply all results by 60 to get the energy in J, but it's not necessary for the comparison)
