Answer:
12.1 units
Explanation:
The problem is asking to find the magnitude of B.
The magnitude of a 3-D vector is given by:
[tex]|V| = \sqrt{x^2+y^2+z^2}[/tex]
where
x, y and z are the components of the vector along the x, y and z directions, respectively
For vector B in this problem,
x = 9.2
y = 4.8
z = 6.3
Therefore, its magnitude is:
[tex]|V|=\sqrt{9.2^2+4.8^2+6.3^2}=12.1[/tex]
