Answer:
1. C(9,4) : n=9, s=4
2. C(10,5) : r=5
3. C(5,5) : n=5
4. C(7,7) : n=6
5. C(18,17) : r=3
Step-by-step explanation:
Answer:
1960 cm^2
Step-by-step explanation:
Surface area:
Area of cross section x 2 = 1/2 x 20 x 21 x 2 = 420 cm^2
Area of slope = 29 x 22 = 638cm^2
Area of base = 22 x 20 = 440cm^2
Area of back = 21 x 22 = 462cm^2
Total Surface area = 462+440+638+420 = 1960cm^2
