  Val cuts a single watermelon into 40 slices, and each slice has 20 black seeds and 20 white seeds. What is the total number of seeds in a watermelon?
conversations.from: assistant
conversations.value: 40 slices per watermelon and each slice having 20 black seeds means each watermelon has 20*40=800 black seeds.
  40 slices per watermelon and each slice having 20 white seeds means each watermelon has 20*40=800 white seeds.
  In total, each watermelon has 800+800=1600 seeds.
  What is the total number of seeds in a watermelon?
