a) This part is already complete I think..
b) This is a cuboid and lateral surface area of cuboid is: 2(lb +bh + hl)
= 2( 10 × 3 + 3 × 7 + 7 × 10)
= 2(30 + 21 + 70)
= 2 × 121 = 242 cm²
Now, the area of top & bottom: lb
= 2 × 10 × 3
= 60 cm²
Neglecting the top & bottom surface area of cuboid:
= 242 - 60
= 180 cm²
c) The total surface area us 242.. I have already done that part above...

Step-by-step explanation:
Answer:
C (900)
Step-by-step explanation:
50 for each orchestra
40 for each balcony
600 x 50 = 30000
39000/40 = 975
600+975=1575 not correct
750 x 50=37500
750 x 40 = 30000
not correct
900x50=45000
600x40=24000
correct
