Doc's Pizza contains 6 pieces of pizza. Ten fourth-graders each bought 20 pizzas from Doc's Pizza and put them in their box. How many pieces of pizza are the children carrying in total? Give the rationale and then the answer.
Let's think step by step. If Each fourth - grader bought 20 pizzas, with each pizza having 6 pieces, each fourth - grader had a total of 20 * 6 = 120 pieces of pizza in their box. Ten fourth - graders each bought 20 pizzas, and since the 20 pizzas had 120 pieces, the total number of pizzas in the students' boxes is 120 * 10 = 1200 pieces.. The answer is: 1200.

A cat spends its time hunting birds. The cat catches 8 birds during the day and twice this many at night. In total, how many birds did the cat catch? Give the rationale and then the answer.

Nancy replaced all of the old vinyl tiles in her bathroom with new hardwood flooring. She replaced flooring in two areas of the bathroom: a 10 foot by 10 foot central area, and a 6 foot by 4 foot hallway. How many square feet of hardwood flooring did Nancy install in her bathroom? Give the rationale and then the answer.
Let's think step by step. 10 feet by 10 feet central area is 10 * 10 = 100 square feet of space. 6 feet by 4 feet hallway is 4 * 6 - 24 square feet of space. Combined, the two areas where she replaced flooring contain 100 + 24 = 124 square feet of space.. The answer is: 124.
