Emma is installing a new tile floor. Each tile measures 12 inches by 12 inches. The room in which she is installing the tiles measures 14 feet by 10 feet. If each tile costs $1.25, how much will it cost Emma to complete her project?

10 * 14 = 140

She'll need 140 tiles.

140 * $1.25 = ?

10*14=140 tiles

140*1.25= $175

140

To calculate the cost of the project, we need to find out how many tiles Emma will need.

First, let's convert the room dimensions from feet to inches. Since there are 12 inches in a foot, the room dimensions in inches are:
Length: 14 feet * 12 inches/foot = 168 inches
Width: 10 feet * 12 inches/foot = 120 inches

Next, we need to find out how many tiles will fit in the room. Since each tile measures 12 inches by 12 inches, we can calculate the number of tiles that will fit in the length and width of the room by dividing the room dimensions by the tile dimensions:
Number of tiles in length = 168 inches / 12 inches = 14 tiles
Number of tiles in width = 120 inches / 12 inches = 10 tiles

To get the total number of tiles, we multiply the number of tiles in length by the number of tiles in width:
Total number of tiles = 14 tiles * 10 tiles = 140 tiles

Lastly, we calculate the cost of the project by multiplying the total number of tiles by the cost per tile:
Cost of the project = 140 tiles * $1.25 per tile = $175.

Therefore, it will cost Emma $175 to complete her project.
