Answer: There are 10,830 dots on 38 ceiling tiles.
Explanation:
To find the total number of dots on 38 ceiling tiles, we can multiply the number of dots on each tile by the number of tiles.
Given that there are 285 dots on each ceiling tile, we can calculate the total number of dots as follows:
Total number of dots = Number of dots per tile × Number of tiles
Total number of dots = 285 dots/tile × 38 tiles
Total number of dots = 10,830 dots
Therefore, there are 10,830 dots on 38 ceiling tiles.
