How Do You Calculate the Area of a Rectangular Glass Rod?

AI Thread Summary
To calculate the area of a rectangular glass rod, one should focus on the surface area rather than just the cross-sectional area. The surface area can be determined by adding the areas of all rectangular surfaces. Given dimensions of 10 cm by 10 cm by 10 meters, the next step involves calculating the area of each face and summing them up. This approach will provide the total surface area of the rod. Understanding these calculations is essential for accurate measurements.

Just add the areas of the rectangular surfaces. I'm assuming you mean surface area.
 
ok, they gave me 10 cm by 10 cm by 10 meters, but I'm not sure what step to take next
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
