Concrete pedestal

The carpenters made wooden mold on a concrete pedestal in the shape of a cube with edge 2 meter long. What is the area in which the concrete touches wooden molds? (No lid or bottom)

Correct result:

S =  16 m2


a=2 S1=a a=2 2=4 S=4 S1=4 4=16 m2a=2 \ \\ S_{1}=a \cdot \ a=2 \cdot \ 2=4 \ \\ S=4 \cdot \ S_{1}=4 \cdot \ 4=16 \ \text{m}^2
