In this question, you are being asked to determine which planes intersect in the cube. Let’s first analyze the points and planes in the diagram:

• Plane LMP: This plane is determined by the points $L$, $M$, and $P$. These points lie on the left side of the cube.
• Plane JKN: This plane is determined by the points $J$, $K$, and $N$. These points form a plane that involves the top-left front face of the cube.
• Plane JKL: The points $J$, $K$, and $L$ form the top face of the cube.
• Plane NOP: Points $N$, $O$, and $P$ form a plane on the bottom face of the cube.
• Plane KLO: The points $K$, $L$, and $O$ define a plane on the right face of the cube.
• Plane JMN: Points $J$, $M$, and $N$ form the front face of the cube.

Answer:

The two planes that intersect are LMP and KLO.

Explanation: These two planes meet along the edge $LP$, where the left side and the right side of the cube intersect.

Tip: When visualizing 3D shapes and their planes, it helps to imagine extending the faces infinitely to understand how they might intersect!
