Volume of cubes = 8 cm³
Measure of each side = √8 cm = 2 cm
The two cubes are placed end to end.
Then,
-----------
Dimensions of the resulting cuboid =>
Length = (2+2) cm = 4 cm
Breadth = Height = 2 cm
Total surface area of the cuboid = 2(lb × lh × bh)
=> [2 × { (4×2) + (4×2) + (2×2)}] cm²
=> [ 2× ( 8 + 8 + 4)] cm²
=> [2 × 20] cm²
=> 40 cm
