For a school play, you are making plastic cubes that are 1.5 feet on each side. How Much plastic is needed to make one cube? If you want to make three cubes, how much plastic is needed?

29 mil

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

can you post the graph?
