Answer:
°
Step-by-step explanation:
It's 20. You start with the parentheses and 8 + 12 is 20. Then you have the brackets next, and so that's 20/4 and that's 5. Then all you have left is 4 x 5 which is 20.
The height would be 36cm. This is the case because to find the height, first multiply the volume by 2 (You are working backwards from the formula). Then divide it by the base edge (15). You will get 36cm.
5 poles will be in 50 yards because 10 x 5 = 50
