Surface are is length times height.
8*8=64
a cube has 6 sides
64*6=384
10 times 60 is 600 so the awnser 600
Answer:
it's 65 because if u count the inside of the boxes u get 65
Step-by-step explanation:
P(t) = 12,000 (2)^(-t/15)
9,000 = 12,000 (2)^(-t/15)
0.75 = 2^(-t/15)
ln(0.75) = ln(2^(-t/15))
ln(0.75) = (-t/15) ln(2)
-15 ln(0.75) / ln(2) = t
t = 6.23
