My answer would be 20.10 which would equal as 21
12+20•3-3x-15
multiply the numbers : 20•3 = 60
12+60-3x-15
group like terms
-3x+12+60-15
add and subtract the numbers : 12+60-15=57
final answer = -3x+57

Answer:
<h2>324 cubes</h2>
Step-by-step explanation:
We calculate how many cubes will fit along each edge:
12 in : 2/3 in = 12 · 3/2 = 18 cubes
2 1/6 in : 2/3 in = 13/6 · 3/2 = 39/12 = 13/4 = 3 1/4 → 3 cubes
4 in : 2/3 in = 4 · 3/2 = 6 cubes
(18)(3)(6) = 324
