Number of bricks = volume of wall/volume of 1 brick --------- (both in same units
<span>volume of wall = (15 × 12)(6 × 12)(1 × 12) in³ -------- convert all in inches </span>

<span>Number of bricks = (15 × 12)(6 × 12)(1 × 12)/(6 × 4 × 2) </span>
<span>= (15 × 12)(6 × 3) </span>
<span>= 3240 </span>
