The measure of the brick wall in inches is given by 14.5 x 12 by 5.5 x 12 by 0.5 x 12 = 174 by 66 by 6
Total volume of the brick wall is given by 174 x 66 x 6 = 68,904 cubic inches.
Volume of each brick = 6 x 4 x 2 = 48 cubic inches.
Therefore, number of bricks needed is given by 68,904 / 48 = 1,435.5 bricks.

Answer:
6
Step-by-step explanation:
6+(6+2)+(6×3)=32
32÷(1+1+3)=6•••••2
So it's 6 and 6+2 and 6 times 3
which is 5 of number 6 plus 2
=6+(6+2)+(6×3)
=6+8+18
=32
Given:
15 students
2 students must be chosen.
No repetition, no order
This is a combinations problem. We use this formula: n! / (n-r)!(r!)
n = 15 ; r = 2
15! / (15-2)!(r!) ⇒ 15! / 13! * 2! = 105
