Question 1003521: The Mazurskys decide to retile their mud room in 16” by 16” tiles. If their mudroom is 3’6” by 10’, how many tiles will they need to purchase? You can cut tiles, but you do not want to glue leftover pieces of tiles together to cover any part of the floor.

You can put this solution on YOUR website!
In inches, one wall of the mudroom measures
+3%2A12+%2B+6+=+36+%2B+6+
+36+%2B+6+=+42+ in
The other wall measures
+10%2A12+=+120+ in
----------------------
If neither of the adjacent walls is exactly
divisible by +16+, then tiles will have to be cut
on both of adjacent walls
----------------------
+42%2F16+=+2.625+
and
+120%2F16+=+7.5+
-----------------
You end up needing +3%2A8+=+24+ tiles
+2%2A7+=+14+ of these tiles do not need to be cut
and +10+ of them will have to cut
------------------------------
Of the +10+ that need cutting, 2 of them get
+.5+ in cut off, 7 of them get +.375+ in
cut off, and there is 1 corner tile that gets
+.5+ cut off one edge and +.375+ in
cut off the adjacent edge
----------------------------------
It really helps to draw a picture to see this
So, you need 24 tiles
