Answer:
36 cm
Step-by-step explanation:
3 cm times 6 cm = 18cm
18 cm times the height (2 cm) = 36 cm
So, the answer is 36 cm for the volume.
-30 + 5a < 16
5a < 46
a < 9.2

312
Volume of the parallalelepiped:
base x width x height
V = 5 x 4 x 12 = 240
for triangular prism:
base = 8-5 = 3
base area = (base x height)/2 = (3x4)/2 = 6
V = base area x 12
V = 6 x 12 = 72
Total volume = 240 + 72 = 312
The polygon has 12 sides
S=(n-2)*180
S=1800
1800=(n-2)*180
n-2=1800/180=10
n=10+2=12
Hence, the polygon has 12 sides
