A packing box of 2.2m x 4.9m x 5.5m is to be completely covered with a plywood. how many square meters of plywood are needed?

Help me please.... Thanks...

The formula for surface area of a rectangular prism is 2ab + 2bc + 2ac.
2ab = 2(2.2m)(4.9m) = 21.56m²
2bc = 2(4.9m)(5.5m) = 53.9m²
2ac = 2(2.2m)(5.5m) = 24.2m²

2ab+2bc+2ac = 99.66m²
