Answer:

Step-by-step explanation:

. Volume of each cube = 64 cm3        

∴ Total volume of the two cubes = 2 × 64 cm3              = 128 cm3      

Let the edge of each cube = x      

∴ x3 = 64 = 43        

∴ x = 4 cm      

Now, Length of the resulting cuboid l = 2x cm            

Breadth of the resulting cuboid b = x cm            

 Height of the resulting cuboid h = x cm      

∴ Surface area of the cuboid = 2 (lb + bh + hl) = 2[(2x . x) + (x . x) + (x . 2x)]              = 2[(2 × 4 × 4) + (4 × 4) + (4 × 2 × 4)] cm2              = 2 [32 + 16 + 32] cm2 = 2[80] cm2 = 160 cm2.
