Final answer:
The possible length of one side of pyramid B's base is approximately 24.41 meters.
Step-by-step explanation:
Let's call the length of one side of pyramid B's base as x. Since pyramid A is similar to pyramid B, the ratio of their volumes is equal to the ratio of the cubes of their corresponding side lengths. We can set up the following equation:
(x/18)^3 = 1224/73
Now we can solve for x:
x = (18 * cuberoot(1224/73))
So the possible length of one side of pyramid B's base is approximately 24.41 meters.
