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.

Step-by-step explanation: 8 divided by 4 is 2.
60% of 6,800 is 4,080 so they sold 4,080. 60
It would be the last answer because if you multiply the percentage 30% times 70 you get 21, and 50% gets you 35.
If both dealers sold 70 total cars, Car Dealer B sold 14 more blue cars.
