Answer:
52m²
Step-by-step explanation:
For this you would consider each face of the figure as a rectangle, and then multiply it by two.
Face 1:
3m×4m×2=24m²
Face 2:
4m×2m×2=16m²
Face 3:
3m×2m×2=12m²
Then you add each of them together to get the overall surface area
12m²+16m²+24m²=52m²
Therefore the final surface area is 52m²
