$\"\"$

The force of the wind blowing aganist a skyscapper can be expressed as $\"\"$ .

Ordered triples, like ordered pairs, can be used to represent vectors.

The geometric interpretation is the same for a vector in space as it is for a vector in a plane.

A directed line segment from the origin $\"\"$ to $\"\"$ is called vector $\"\"$ , corresponding to vector $\"\"$ .

The distance from the origin $\"\"$ to a point $\"\"$ is $\"\"$ .

The magnitude of vector $\"\"$ is $\"\"$ .

$\"\"$

Therefore, the approximate magnitude of the force is $\"\"$ .

$\"\"$

The correct choice is A.
