the surface area of a rectangular prism is:
A = 2( (23) + (42) + (4*3) ) = 2( 6 + 8 + 12 ) = 2(26) = 52 so the answer for the first one is : 52in.^2 
and for the second one u should know the surface area of a cube is:
6x ^2 so the answer is:
6x^2 square unites :)))
i hope this is helpful
have a nice day

1.) Surface Area:

Formula: A= 2(wl+hl+hw)

A= 2(23+43+4*2)
A= 2(6+12+8)
A= 2(26)
A=52.

2.) Cube Surface Area
     Formula:  A=6\(a^{2}\)

thus, 6\(x^{2}\) square units.
