If three cubes of side 8 cm are joined together side by side,

dimensions of resulting cuboid are

length = 8*3 = 24 cm

breadth = 8cm

height = 8cm

TSA = 2(lb+bh+lh)

= 2(24×8+8×8+24×8)

= 2(192+64+192)

= 2×448

=**896 cm²**

dimensions of resulting cuboid are

length = 8*3 = 24 cm

breadth = 8cm

height = 8cm

TSA = 2(lb+bh+lh)

= 2(24×8+8×8+24×8)

= 2(192+64+192)

= 2×448

=

The dimensions of the resultant cuboid are:

Length = 8 + 8 + 8 = 24 cm

Breadth = 8 cm

Height = 8 cm

Total surface area of cuboid = 2(LB + BH + HL)

= 2 [(24*8) + (8*8) + (8*24)]

= 2[192 + 64 + 192]

= 2[448]

= 896

Total surface area = 896 sq cm.
