Answer:
2144 cm²
Step-by-step explanation:
Here Length of Cuboid = 26 cms
Breadth of Cuboid = 20 cms
Height of Cuboid = 12 cms
We know that Surface area of Cuboid (Total)
= 2 (length × breadth + breadth × height + height × length)
= 2( 26×20 + 20×12 + 12×26)
=2(520 + 240 + 312)
= 2 × 1072
= 2144 cm²
∴ Surface Area of guven Cuboid is 2144 cm²
