a=5 cm
If two cubes are joined end to end it becomes cuboid.
Dimensions of cuboid are
Lengh =l=10 cm
Breadth =b=5 cm
height =h=5 cm
Lateral surface Area = 2(l+b)h=2(10+5)5
=2×15×5=15059cm
Total surface Area = 2(lb+bh+lh)
=2(10×5+5×5+5×10)
=2(50+25+50)
=2(125)
=250sq.cm
Volume = lbh=10×5×5=250 cubic cm

Answer:
The question is incomplete.... what's the number of cube you haven't mentioned! So, I am assuming number of cubes = 2 in a row.
volume of cube = a³ = 125 => a = 5 cm
so if the 2 cubes are joined then they will form cuboid.
Surface Area of cuboid = 2(lb+bh+hl)
Length = 10 cm
Breadth = 5 cm
Height = 5 cm
2(50+25+50) = 2(125) = 250 cm²
Hope it will help you!
