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? Let's answer step by step:
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?. The answer: 1600.
