$\huge{\sf{\underline{\boxed{\red{Answer :-}}}}}$

Given:

⇒Volume of cubes = 64 cm^3

⇒ (Edge)^3 = 64

⇒ Edge = 4 cm

If cubes are joined end to end, the dimensions of the resulting cuboid will be

4 cm, 4 cm, 8 cm.

Surface area of cuboids =2(lb+bh+lh)

=2(4×4+4×8+4×8)

=2(16+32+32)

=2(16+64)

=2(80)=160 cm^2
