Please help. A cube has sides of length √5. I need to find the area of one side of the cube. Find the volume of the cube. find the length of the diagonal of the sides.
area is radical 5 times radical 5
the volume is \[\left( \sqrt{5} \right)^{3}\]
and to find the diagonal line you have to use the pythagorean theorem
that diagonal line is the hypoteneus and the radical 5's are the two sides thus that...
How would I find the distance from A to B in a figure they show in the textbook?
the diagonal line?
yes, it is a digagonal line from one corner to the other corner
since its a cube...we can assume that one side of the cube is a perfect 2 dimentional square...so each side is \[\sqrt{5}\]
you notice that each side of the square of one side of the cube is measured the same thus all the sides are radical 5
use the pythagorum theorem to find what the diagonal line's length is
you are trying to find \[c ^{2}; \in the formula a ^{2}+b ^{2}=c ^{2}\]
you have a^2 and b^2 already
How do I do that when there are no numbers provided. It is just A to B.
well it tells you in the problem that the side of the square is \[\sqrt{5}\]
this applies to all the side so the cube
So to figure it out I would use √5²+√5²=c²
yes
Thank you very much. Hopefully I can figure this out.
i wish you the best of luck :)
