Alrighty so to get the surface of the rectangle your going to multiply the base : 4x2=8
then 4x2 again = 8 8+8=16 then the sides 6x2=12 12x4(4 is the four long sides of the prism) = 48. 16+48= 64 cm

1. 64 cm2

For the triangular prism you will multiply 3x4 to get 12 then divide 12 in half because for the triangle area formula it is LxW/2
So 6 then 6x2 to get the other side so 12
Then the top part 2x5 = 10
Then the base 4x2=8
Then add it all together : 12+10+8= 30cm2

2. 30cm.

Then to get all together just add 64+30= 94cm2

3. 94cm2
