ts of cuboid =2(lb+bh+hl)
=2(20×15+15×10+10×20)
= 2(300+150+200)
= 2(650)
= 1300

Answer:
The total surface area of the cuboid is 1300 cm² .
Step-by-step explanation:
Formula
Total surface area of a cuboid = 2 (Length × Breadth + Breadth × Height + Height × Length)
As given
The length,breadth and height of a cuboid are 20cm ,15cm ,10cm respectively.
Total surface area of a cuboid = 2 × (20× 15 + 15 × 10 + 10 × 20)
= 2 × (300 + 150 + 200)
= 2 × 650
= 1300 cm²
Therefore the total surface area of the cuboid is 1300 cm² .
