Answer:
Given that
Volume of Cube = 64cm³
(Edge)³ = 64cm³
Edge = ³√64 cm³
Edge = 4 cm
If the Cubes are join end to end , the dimensions of the resulting cuboid will be 4 cm,4 cm, 8 cm.
Therefore, the Surface area of cuboids = 2(lb + bh + hl)
=2( 4 x 4 + 4 x 8 + 4 x 8)
=2( 16 + 32 + 32)
=2( 16 + 64)
=2(80)
= 160 cm²
Hence, Surface Area of resulting cuboid is 160 cm².
