10. (5 points) There is a group of students forming a hollow square, with the outermost layer consisting of 52 people and the innermost layer consisting of 28 people. The group of students has people.
【Solution】Solution: Number of layers of the square formation: $(52-28) \div 8+1$
$$
\begin{array}{l}
=3+1 \\
=4 \text { (layers); }
\end{array}
$$

Number of people on each side of the outermost layer: $52 \div 4+1$
$$
\begin{array}{l}
=13+1 \\
=14 \text { (people); }
\end{array}
$$

Total number of people: $(14-4) \times 4 \times 4$
$$
\begin{array}{l}
=10 \times 16 \\
=160 \text { (people); }
\end{array}
$$

Answer: This team of students has a total of 160 people.
