Mrs. Lopez wants to retile her 16 ft by 18 ft dining room.
a. How many 1 sq ft tiles does she need? I calculated 288 tiles
b. She changes her mind and wants to use 4 in by 4 in square tiles. How many square tiles does she need? I'm stump on how to answer this part of the question
a. correct
b. 1 foot = 12 inches = 4" * 3
Therefore each square foot tile = 3 * 3 4-inch square tiles.
Can you take it from there?
2592
To find the answer to part a. and calculate how many 1 sq ft tiles Mrs. Lopez needs, we can use the formula for finding the area of a rectangle:
Area = length x width
In this case, the length is 16 ft, and the width is 18 ft. So we can calculate the area of the dining room as follows:
Area = 16 ft x 18 ft = 288 sq ft
Therefore, Mrs. Lopez needs 288 1 sq ft tiles to retile her dining room.
Now, let's move on to part b. where Mrs. Lopez wants to use 4 in by 4 in square tiles. To determine how many square tiles she needs, we'll need to convert the measurements to the same units.
Since the dimensions are given in feet, we need to convert the 4 inch by 4 inch square tiles to feet. There are 12 inches in a foot, so one square foot is equal to (12 inches) x (12 inches) = 144 square inches.
To convert the 4 in by 4 in square tiles to square feet, we divide the area of each tile by the conversion factor:
(4 inches x 4 inches) ÷ (144 square inches/square foot) = 16 square inches ÷ 144 square inches/square foot = 0.1111 square feet
Now, we can calculate the total number of square tiles needed by dividing the area of the dining room (288 square feet) by the area of each tile (0.1111 square feet):
Number of square tiles = 288 sq ft ÷ 0.1111 sq ft ≈ 2592
Therefore, Mrs. Lopez will need approximately 2592 4 in by 4 in square tiles to retile her dining room.
