Answer:
1/6^4.
Step-by-step explanation:
Multiply denominators.
6*6*6*6 = 1,296
Your answers are 1/6^4 and 1/1296.
Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
