Final answer:
The question involves vector calculus and concepts such as the volume of a parallelepiped and vector field integrals. It also tangentially discusses vector addition and subtraction in the context of fencing land.
Step-by-step explanation:
The question seems to revolve around vector calculus and the application of the cross product in determining the volume of a parallelepiped. Specifically, it involves evaluating the expression (B x C). A where A, B, and C are vectors denoting the edges of the parallelepiped.
This expression calculates the scalar triple product, which gives the volume of the parallelepiped formed by the vectors. A correct calculation would involve taking the cross product of vectors B and C and then taking the dot product of the result with vector A.
Concerning the boundary of the square with vertices (0, 0), (3, 0), (0, 3), and (3, 3), it appears the student may be asked to evaluate a line integral around the square or apply Gauss's Theorem if the context involves a vector field. Without additional context or the specific expression or function to be integrated, further explanation is not possible.
The information about the landowner fencing suggests a question related to vector addition and subtraction to find the length and orientation of a resultant fence side, given the other sides as displacement vectors.
