Dave wants to make a stone walkway. The rectangular walkway is 4 feet wide and 4 feet long. Each 2 foot by 2 foot stone covers an area of 4 square feet. How many stones will Dave need to make his walkway?
4 * 4 = 16 square feet
16/4 = 4
What the hell
16
18. Because 126/7=18. And 130-4=126
To find out how many stones Dave will need to make his walkway, we need to calculate the area of the walkway and then divide it by the area covered by each stone.
First, let's calculate the area of the walkway. The walkway is rectangular, with a width of 4 feet and length of 4 feet. The area of a rectangle is calculated by multiplying the length by the width, so in this case, the area is 4 feet x 4 feet = 16 square feet.
Now that we know the area of the walkway is 16 square feet, we can calculate how many stones Dave will need. Each stone covers an area of 4 square feet (2 feet x 2 feet). To find out the number of stones needed, we can divide the area of the walkway by the area covered by each stone.
16 square feet / 4 square feet per stone = 4 stones.
Therefore, Dave will need 4 stones to make his stone walkway.
