Three cubes of each side 4 cm are joined end to end. Find the surface area of the resulting cuboid.
Given,
Edge of each cube = 4cm
After joining 3 cubes end to end a cuboid is formed
Length of cuboid = 4+4+4 = 12 cm
Breadth of cuboid = 4 cm
Height of cuboid = 4cm
Surface area of cuboid = 2(lb+bh+hl)
= 2(48+16+48)
= 224 cm2
