Answer:

Volume: 864

Surface Area: 684

Explanation:

Volume:


(1)/(2)(9 * 16 * 12) = 864

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.
