The surface area of a cube with edge 23±0.0004 cm is 3174±0.11 cm.
The surface area is edge squared times 6. The surface area at 23.0004 is 3174.1104. The surface area at 22.9996 is 2173.8896.
If measured top the nearest centimetre then the answer is 0.5 cm.
The greatest possible error is 0.005
The greatest possible error is 0.0005
what is the greatest possible error of 350mi
erroneousErroneous or error-ridden are two possible answers.
Assuming that the measurement is to the nearest 0.01, the greatest possible error is 0.005.
If the numbers are rounded to the nearest 750, then 375 is the greatest possible error. Although you are not likely to have counted in 750s, it is quite possible that you counted in 50s (greatest error = 25). Or in tens (GE = 5) or in units (ones), when the greatest error is 0.5. The greatest possible error is half of the smallest unit of measurement.
The greatest possible error is 49. 147, rounded to the nearest 98 is 98 with an error of 49. Similarly, 49.0...1, rounded to the nearest 98 is 98 with an error of 48.999... recurring.
This is called parallax error.
