Alex plans to make a mosaic for his art class. How many one inch square tiles will he need to cover a surface that is 2 feet by 3 feet?
24 * 36 = 864 square inches
To find out how many one-inch square tiles Alex will need to cover the surface, we need to convert the measurements from feet to inches.
Since 1 foot is equal to 12 inches, the surface dimensions in inches will be:
- Width: 2 feet * 12 inches/foot = 24 inches
- Length: 3 feet * 12 inches/foot = 36 inches
Now, let's calculate the total number of tiles:
- Area of the surface = Width * Length
- Area = 24 inches * 36 inches = 864 square inches
Since each tile is one square inch, Alex will need 864 tiles to cover the surface.
To find the number of one inch square tiles needed to cover a surface, we first need to convert the dimensions of the surface to inches. Since there are 12 inches in a foot, we can multiply the length and width of the surface in feet by 12 to get the dimensions in inches.
Length in inches = 2 feet * 12 = 24 inches
Width in inches = 3 feet * 12 = 36 inches
Now that we have the dimensions of the surface in inches, we can calculate the total number of one inch square tiles needed by multiplying the length and width together.
Total number of tiles = Length in inches * Width in inches = 24 inches * 36 inches = 864 tiles
Therefore, Alex will need 864 one inch square tiles to cover a surface that is 2 feet by 3 feet.
