The surface area of a cube can be found by multiplying the length of one side by itself and then multiplying that result by 6 (since a cube has 6 equal sides).
In this case, the length of one side is 0.9 m.
0.9 m * 0.9 m = 0.81 m²
0.81 m² * 6 = 4.86 m²
Therefore, the surface area of the crate is 4.86 m².
None of the given answer choices match this result exactly, but the closest option is 4.5 m² (answer b).
