To sum up, we only have the length of one side.
We need to find the width of the same side. -
20.5 x 20.5 = 420.25
To get the surface area, we multiply by six.
<u>Why?</u> There are six sides on a cube.
420.25 x 6 = 2521.5

To answer this question, use the following:
According to pythagorean theorem, the hypotenuse of the triangle, c, with legs a and b, can be found with the following equation:

Thus plugging in 3 for a and 4 for b:


The question is, what kind of numbers could be rounded up to 500 000?
Depending on how we round, if we round to 1 000, then:
from 499 500 till 500 499
if we round to the nearest 10 000 then: (I find this most probable)
495 000 to 504 999
if we round up to the nearest 100 000:
450 000 to 549 999
