Answer:
132cm²
Step-by-step explanation:
Split into two shape: Cube & Triangle prism
Cube surface area:
1) area of top & bottom
(4×3)×2= 12×2= 24cm²
2) area of the sides (only three sides as for surface)
(3×6)×3= 18×3= 54cm²
Triangle prism surface area:
1) area of two sides of triangle:
(½×6×4)×2= (3×4)×2= 12×2= 24cm²
2) area of two sides of rectangle:
(5×3)×2= 15×2= 30cm2
Total surface area: 24+54+24+30= 132cm²
