Answer:

SA = 52 ft²

Step-by-step explanation:

The opposite faces of the prism are congruent , then

SA = 2(3 × 2) + 2(2 × 4) + 2(3 × 4)

     = 2(6) + 2(8) + 2(12)

     = 12 + 16 + 24

     = 52 ft²

Answer:

52

Step-by-step explanation:

Surface area = sum of faces areas

SA of a rectangular prism = 2 ( lw + wh + lh )

where l = length, w = width and h = height

The prism has the following dimensions

l = 3

h = 4

w = 2

That being said we want to plug in these dimensions into the formula

SA = 2 ( 3*4 + 4*2 + 2*3 )

3*4=12

4*2=8

2*3=6

SA = 2 ( 12 + 8 + 6 )

12 + 8 + 6 = 26

SA = 2(26)

SA = 52
