2(12*3+12*6+12*3)
2(36+72+36)
2*144
288 m^3
Step-by-step explanation:
The best and most correct answer among the choices provided by your question is the third choice or letter C.
<span>If ST = 21, SP = 3b – 11, and PT = b + 4, the value of b would be 14.

largest angle: 3x
smallest angle: x
third angle: 3x - 23
The sum of the angles of a triangle equals 180°
(3x) + (x) + (3x -23) = 180
7x - 23 = 180
7x = 203
x = 29
largest angle: 3x = 3(29) = 87
third angle: 3x - 23 = 3(29) - 23 = 87 - 23 = 64
Answer: 29°, 64°, 87°
