Use "converting units"
Mrs. fallis wants to tile the kitchen counter that has an area of 2 square meters. She has 2000 square tiles with 3 cm sides. Does she have enough tiles to cover the counter? Explain.
To determine if Mrs. Fallis has enough tiles to cover the kitchen counter, we first need to convert the area of the counter to the same unit as the tiles.
The counter has an area of 2 square meters. Since each square meter is equivalent to 10,000 square centimeters, we can convert the counter's area:
2 square meters = 2 x 10,000 square centimeters = 20,000 square centimeters
Now, let's analyze the size of the tiles. Each tile has sides of 3 cm, which means it has an area of 3 cm x 3 cm = 9 square centimeters.
To determine the number of tiles needed, we divide the total area of the counter by the area of each tile:
Number of tiles needed = 20,000 square centimeters / 9 square centimeters = 2,222.22
Since we can't have a fraction of a tile, we round up to the nearest whole number, which is 2,223 tiles.
Given that Mrs. Fallis has 2,000 tiles, she does not have enough tiles to completely cover the kitchen counter. She is short by 2,223 - 2,000 = 223 tiles.
