Step-by-step explanation:
if you divide 20 by 8, then you get 2.5. multiply that by six, and you get your answer.
Answer:
The surface area of the prism is 108 square in.
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
Area = length *width
102 = 17*w
w = 102/17 = 6
l=17
w=6
perimeter = 2l +2w
p = 2(l+w)
p=2*23
p = 46 cm
