According to the condition of the problem, the tank has a cubic shape. And this means that its length = width = height = a.
Then its volume will be equal to:
V = a ∙ a ∙ a = a ^ 3.
For our option, a ^ 3 = 8 (m3).
Let’s find the length of the edge of the tank:
a = ∛8 = 2 (m).
Answer: The rib length of this tank is 2 m.
