Two cubes, each of volume 512 cm3 are joined end to end. Find the surface area of the resulting cuboid.
Volume of each cube = 512 cm3
Let length of edge of each cube = a cm
When these two cubes are joined end to end a cuboid is formed :
Length of cuboid = 8+8 = 16 cm
Breadth = 8 cm
Height = 8 cm
Surface area of resulting cuboid =
