ANSWER
Let the side of a cube =a
Volume of the cube = a^3
a^3 = 125
a^3 = 5^3
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
Hope this will help you
