Answer:
3060 cm^2
Step-by-step explanation:
First, let's find the areas of the trapezoids.
Next, let's find the area of the bases (the top rectangle and bottom rectangle).
- Top: 6 × 30 = 180
- Bottom: 34 × 30 = 1020
- 1020 + 180 = 1200.
After that, we find the surface area of the side rectangles.
- 17 × 30 = 510
- 25 × 30 = 750
- 510 + 750 = 1260.
Lastly, we add 1260, 1200, and 300 together.
Therefore, the surface area should be 3060 cm^2.

Answer:
92
Step-by-step explanation:
x= the ideal mark for his third test
100 + 63 + x/3 = 85
163+x=85x3
163 + x = 255
x=92
He would need to get at least a 92 to have the 85 average.
