To find the length of a vector, simply take the square root of the sum of the squares, $$\ \huge \sqrt{4+16+25}$$. This, $$\ \huge \sqrt{45}$$, or $$\ \huge 3\sqrt{5}$$. Does that make sense to you?

so it would be $3\sqrt{5} \right?$

Length of vector: $$\ \huge \sqrt{x^2 + y^2 + z^2} .$$

Yes, $$\ \huge 3\sqrt{5}$$.
