Answer:
408
Step-by-step explanation:
Surface area formula is A=2(wl+hl+hw)
Substituting these values into the formula you would get
2·(3·8+4·8+4·3)=136
136 accounts for one rectangular prism.
Since you have 3 multiply 136 by 3 which would leave you with 408
74 = 20(2.5) + 20(x)
74 = 50 + 20x
74-50 = 20x
24 = 20x
24/20 = x
1.2 = x
x = 1.2 yards of red felt
