You have to use a proportion.
3.5/18= 1.5/x
3.5x=27
x= 7.7 cm
Answer:
Volume: 864
Surface Area: 684
Step-by-step explanation:
Volume:

Surface-Area: (Pretty Self-explanatory)
1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)
2. Base - 16 * 9 = 144
3. Height/Base - 12 * 16 = 192
4. 15 * 16 = 240
192 + 144 + 108 + 240 = 444
The Surface Area is 684.
