1: 8 faces and 9 with the base 9 vertices and 16 edges
2: 3 faces and 5 with the bases 6 vertices and 9 edges
3: 3 faces and 4 with the base 4 vertices and 6 edges
Rad times height' and you get it
Ok so assuming you don't get tired and the rate stays the same
rate=amountwork/timeitdonein
rate=800/15
euals
6000/time
800/15=6000/time
simlify for ease
160/3=6000/time
multiply both sides by 3time
160time=18000
divide both sides by 160
time=112.5
means 112.5 minutes or 1hour, 52 minutes, 30 seconds
A. 800/15=6000/t or
15/800=t/6000
B. solved, 112.5 minutes
