Question 1003521
In inches, one wall of the mudroom measures
{{{ 3*12 + 6 = 36 + 6 }}}
{{{ 36 + 6 = 42 }}} in
The other wall measures
{{{ 10*12 = 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
----------------------
{{{ 42/16 = 2.625 }}}
and
{{{ 120/16 = 7.5 }}}
-----------------
You end up needing {{{ 3*8 = 24 }}} tiles
{{{ 2*7 = 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
