Side of cube = 5 cm
No. of cubes joined = 3
Now,
Length of cuboid = 5 + 5 + 5 = 15 cm
Breadth of cuboid = 5 cm
Height of cuboid = 5 cm
Total surface area of cuboid = 2(lb + bh + lh)
= 2((15)(5) + (5)(5) + (15)(5))
= 2(75 + 25 + 75)
= 2*175
= 350 cm²
Therefore surface area of resulting cuboid is 350 cm²
Hope this helps you....:)
