Answer:
Step-by-step explanation:
Edge of cube (A) = 3 cm.
Length of resulting cube = 5 × 3 = 15 cm
Height of resulting cuboid = 3 cm
And,
Breadth of resulting cuboid = 3 cm
TSA of resulting cuboid = 2(lB + BH + HL)
=> 2 ( 15 × 3 + 3 × 3 + 3 × 15)
=> 2 ( 45 + 9 + 45)
=> 2 × 99
=> 198 cm².
Hence,
TSA of resulting cuboid = 198 cm².
