conversations.value: A community is building a metal fence. Each fence panel is made of 3 metal sheets, and 2 metal beams. The fence is made of 10 fence panels. If each sheet is made of 10 metal rods and each metal beam is made of 4 metal rods, how many metal rods does the community need for the fence?
  Give me a clear explanation.

conversations.value: In each panel, the metal sheets use 3 metal sheets * 10 metal rods = 30 metal rods.
  In each panel, the metal beams use 2 metal beams * 4 metal rods = 8 metal rods.
  So each panel uses 30 + 8 = 38 metal rods.
  The entire fence therefore needs 38 metal rods * 10 fence panels = 380 metal rods.
