find the surface area of the cube shown.

As we know that surface area of the cube is given by the formula
Surface Area (SA)=[tex] 6a^2 [/tex]
where a is the side length of the cube .
As we can see in the diagram the side length of the cube is [tex] a=5.5cm [/tex]
Hence the surface area of the cube will be
[tex] SA=6*(5.5)^2\\\\SA=6*30.25 cm^2=181.5 cm^2\\ [/tex]
