Step-by-step explanation:

hey mate ////

here is ur answer/////////////////////////////////////////////////////

given, that volume of two cubes=64

edge=$\sqrt[3]{64\\}$

edge=4 cm

length (l) = side + side = 4+4 = 8 cm

breadth(b) = side = 4 cm

height(h) = side = 4 cm

TSA of cuboid=2[lb+bh+hl]

=2[8*4+4*4+4*8]

2[32+16+32]

2[80]

160cm2
