Question

in the cube shown below, which planes are parallel? select all that apply.

Explanation:

Step1: Recall parallel - plane concept

In a cube, opposite faces are parallel planes.

Step2: Analyze each option

• For "BEF and FGH": These are not parallel.
• For "BEF and CDG": These are parallel as they are opposite - like planes in the cube.
• For "CDG and DEH": These are not parallel.
• For "BCF and BCD": These are not parallel.

Answer:

BEF and CDG
