in the cuboid,
l= 12+12=24 cm
b= 12cm
h=12 cm
tsa of cuboid = 2(lb+bh+hl)
= 2[(24×12)+(12×12)+(12×24)]
= 2(288+114+288)
= 2×720
= 1440cm^2
l= 12+12=24 cm
b= 12cm
h=12 cm
tsa of cuboid = 2(lb+bh+hl)
= 2[(24×12)+(12×12)+(12×24)]
= 2(288+114+288)
= 2×720
= 1440cm^2

Answer:
1440 cm²
Step-by-step explanation:
For the resulting cuboid,
l = (12 +12) cm
= 24 cm
b = 12 cm
h = 12 cm
∴ Surface area of the resulting cuboid
= 2(24 × 12+12 ×12+12 × 24)
= 2 × 720
= 1440 cm²
Hence, 1440 cm² is surface area of resulting cuboid.
