AI Thread Summary
The volume of the pyramid, based on a base area of 20.4 acres and a height of 69 ft, was calculated to be approximately 28,370.082 m³ after conversion. The formula used was V = (1/3)bh, where the base area in square feet was converted to cubic meters. There was some confusion regarding the correct base area conversion, but the final volume was confirmed. Participants emphasized the importance of showing all steps in calculations to avoid errors. The discussion concluded with the acknowledgment of the simplicity of the problem once the correct approach was taken.

Homework Statement



The base of a pyramid covers an area of 20.4 acres (1 acre = 43, 560 ft^2) and has a
height of 69 ft.

Find the volume of this pyramid in cubic meters. Answer in units of m3.

Homework Equations



V of Pyramid= (1/3)bh

where 'b' is 43,560 ft^2


The Attempt at a Solution



My attempt at the solution got me 28370.082 cubic meters after converting.
 
Physics news on Phys.org
Don't you mean b= 43,561*20.4 ft2?

Also how many m= 1 ft?
 
Yes that's what i meant. I just redid my solution. Several figures off lol. But please, attempt the problem so i can check my answer

might i add that the question wants the answer in sigfigs

also about the conversions. let's just find the answer in cubic feet first. the conversion can be done afterwards

I was asking because I didn't know.

V=1/3*20.4*43560*69

and according to google 1ft2=0.0283168466 m3

so I get 578,749.7m3
 
thanks that's what i got. this problem was extremely simple i was just exhausted and tried skipping steps foolishly.

guess its time to close this thread
 

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...
