Answer:
144
Step-by-step explanation:
You need to know the Order of Operations. First you do 2 to the power of 4 (because it's the E in PEMDAS) which is 2*2*2*2 which equals 4, 8, 16, then you would do three squared which is 3*3 which equals 9. Multiply (M in PEMDAS) 16 by 9 which would come out to 144 or how I would multiply those two numbers is 9*10 + 9*6 or 90 + 54 with a final answer of 144.

<em>Additional comment</em>
The total <em>price</em> is a different matter:
$12(2) +$7(16) = $136 . . . for 2 adult and 16 kids
12a +7k . . . for 'a' adults and 'k' kids
Number of sands needed = 36 x 20 x 2/12 = 120 cubic feet.
