Total surface area = 38 cm²
Step-by-step explanation:
The given information is,
→ Length (l) = 4 cm
→ Breadth (b) = 3 cm
→ Height (h) = 1 cm
Formula we use,
→ 2(lb + bh + lh)
The surface area of cuboid will be,
→ 2(lb + bh + lh)
→ 2{(4 × 3) + (3 × 1) + (4 × 1)}
→ 2(12 + 3 + 4)
→ 2 × 19
→ [ 38 cm² ]
Hence, the surface area is 38 cm².
