176. An interesting cube. What is the length of the edge of a cube (in meters) for which:
1) the total surface area and volume are expressed by the same number
2) the total surface area is equal to the square of the volume;

3 the square of the total surface area is equal to the volume?
176. 1) \(6 \text{m}\); 2) approximately \(1.57 \text{m}\); 3) \(\frac{1}{36} \text{m}\).
