Answer 1

Answer:

256

Step-by-step explanation:

Here we have two square and one invisible part (where those square are touching)

The 1st square has dimension:

4x4x5

The 2nd hs dimension: 8x4x5

The formula of surface are for square is

S=2B+M

For first

S1=2x4x5+2x4x5+2x4x4=40+40+32=112

For 2nd

S2=2x5x4+2x5x8+2x4x8=40+80+64=184

The invisible part is are 4x5=20 which we added in s1 and also in s2, so we have to remove.

The all area is:

s1+s2-2x20=112+184-40=256
