Edge of cube = 8cm
Length of the cuboid after joining = 8+8 = 16cm
Breadth of the cuboid = 8cm
Height of the cuboid = 8cm
Surface area of the cuboid
= 2 (lb+lh+bh)
= 2 (16*8 + 16*8 + 8*8 )
= 2 (128+128+64)
= 2 (320)
= 640 cm²

EDGE OF CUBE= 8cm
VOLUME OF CUBE = a³ = (8)³ = 512 cm³
LENGTH OF RESULTING CUBOID = 8+8 = 16 cm
BREADTH OF RESULTING CUBOID = 8 CM
HEIGHT OF RESULTING CUBOID = 8CM
TSA OF RESULTING CUBOID = 2(LB+BH+HL)
= 2(16×8+8×8+8×16)
= 2( 128+64+128) = 2×320 = 640 cm³
