Volume of each cube = 64 cm³
side³ = 64
side³ = 4³
Hence, side = 4 cm
Now if two cubes are joined together it will form a cuboid.
Length of the resisting cuboid,
l = 2 × side cm
l = 2 × 4
l = 8 cm
Breadth, b = 4cm
Height, h = 4cm
Hence surface Area
SA = 2 ( lb + bh + hl )
SA = 2 ( 8×4 + 4×4 + 4×8 )
SA = 2 ( 32 + 16 + 32 )
SA = 2 ( 64 + 16 )
SA = 2 × 80
SA = 160 cm²
