Explanation
Explanation To solve this problem, we can calculate the rate at which the laborers dig the earth: Rate = 805 cubic meters / (35 laborers × 5 hours) = 805 / 175 = 4.6 cubic meters per laborer per hour Now, we can calculate the amount of earth dug by 30 laborers in 6 hours: Earth dug = 30 laborers × 6 hours × 4.6 cubic meters per laborer per hour = 30 × 6 × 4.6 = 828 cubic meters The correct answer is 828m³ .
