Solution Steps

Problem 1: True or False Statements

We analyze the statements regarding their spatial relationships.

1. CH is parallel to DG: False
2. AG is parallel to CE: True
3. DF intersects HB: True
4. DF is parallel to GF: False
5. BC intersects HE: True

Problem 2: Cube with Edge Length of 2 cm

Distance between A and G can be calculated using the space diagonal formula: $\text{Space diagonal} = a\sqrt{3}$ $\text{Distance} = 2\sqrt{3} \approx 3.46 \, \text{cm}$

Problem 3: Cube with Edge Length of 4 cm

Distance between A and H can be calculated using the space diagonal formula: $\text{Space diagonal} = a\sqrt{3}$ $\text{Distance} = 4\sqrt{3} \approx 6.93 \, \text{cm}$

Problem 4: Distance in 3D Space

Given T is the midpoint of AB in a cube with edge length 5 cm. Distance between T and B can be calculated using the Pythagorean theorem: $\text{Midpoint} = \left( \frac{5}{2} \right) = 2.5$ $\text{Distance} = \sqrt{(2.5)^2 + (5)^2} = \sqrt{6.25 + 25} = \sqrt{31.25} \approx 5.59 \, \text{cm}$

Problem 5: Distance Along a Line

Distance between G and E in a cube with edge length 2 cm: $\text{Face diagonal} = a\sqrt{2}$ $\text{Distance} = 2\sqrt{2} \approx 2.83 \, \text{cm}$

Problem 6: Distance in 3D Space

Given the distance between AG and EF in a cube with edge length 12 cm. Assuming AG is the space diagonal and EF is a line segment in the same plane: $\text{Space diagonal} = a\sqrt{3}$ $\text{Distance} = 12\sqrt{3} \approx 20.78 \, \text{cm}$
