= b
There are 18 blocks across width and 48 blocks run up and down the length of quilt.
<u>Solution:</u>
Given, A quilt is 72 inches wide and 96 inches long.
The blocks have 4 inch sides
<em><u>Finding number of blocks run across the width of quilt:</u></em>


<em><u>Finding number of blocks run across length:</u></em>


<em><u>Finding number of blocks run up and down the length of the quilt:</u></em>


Hence, there are 18 blocks across width and 48 blocks run up and down the length of quilt
