I can help you solve the questions from the image you uploaded. Here are the eight geometry problems involving cubes, pyramids, and cuboids. Let’s go step by step to solve them.

### **Problem 1:**

Given a cube \( ABCD.EFGH \) with an unknown side length. Point \( P \) is at the midpoint of side \( DC \). Find the distance from point \( B \) to point \( P \).

### **Solution:**
1. Assume the side length of the cube is \( s \).
2. Coordinates of relevant points:
   - \( B(s, 0, 0) \) (since point B is on the front bottom-left corner).
   - \( D(0, s, 0) \), \( C(s, s, 0) \) (since these are on the bottom face).
   - Point \( P \), the midpoint of \( DC \), has coordinates \( \left(\frac{s}{2}, s, 0 \right) \).
3. Distance formula:
   \[
   d_{BP} = \sqrt{(s - \frac{s}{2})^2 + (0 - s)^2 + (0 - 0)^2}
   = \sqrt{\left(\frac{s}{2}\right)^2 + s^2} = \sqrt{\frac{s^2}{4} + s^2}
   = \sqrt{\frac{5s^2}{4}} = \frac{s\sqrt{5}}{2}
   \]
Thus, the distance \( d_{BP} = \frac{s\sqrt{5}}{2} \).

### **Problem 6:**

Given a cube \( ABCD.EFGH \) with an edge length of \( \sqrt{3} \) cm, and point \( T \) on \( AD \) such that \( AT = 1 \) cm, find the distance from point \( A \) to point \( B \) along line \( BT \).
