To find the length of the spider's thread, we need to find the length of the diagonal of the tank.
Using the Pythagorean theorem, we can find the length of the diagonal.
The length of one side of the tank is given by the line from the top-right back corner to the bottom-right back corner.
We can see that the length of this side is 28 inches.
Similarly, the length of the other side of the tank is given by the line from the top-right back corner to the top-right front corner.
We can see that the length of this side is 36 inches.
Using the Pythagorean theorem, we can find the length of the diagonal (d) of the tank:
dĀ² = 28Ā² + 36Ā²
dĀ² = 784 + 1296
dĀ² = 2080
d = ā2080
d ā 45.6 inches.
Therefore, the length of the spider's thread would need to be approximately 45.6 inches.
