Answer:
Thursday's attendance was 9,315 visitors.
Step-by-step explanation:
Given that the number of visitors triple each day.
Given that attendance on Monday = 345 visitors.
Tuesday's attendance = 3 x Monday's attendance = 3 x 345.
Wednesday's attendance = 3 x Tuesday's attendance = 3 x 3 x 345.
Thursday's attendance = 3 x Wednesday's attendance = 3 x 3 x 3 x 345 = 27 x 345 = 9,315 visitors.
Hence, Thursday's attendance was 9,315 visitors.

Answer:
1164
Step-by-step explanation:
Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.
384 + 600 + 192 = 1164
