Question:
two cubes each of edge 6cm are joined face to face find the surface area of the cuboid thus formed
Answer:
Given, edge of the cube is 6 cm
When two cubes are joined end to end, then the resulting solid is cuboid.
Now,
Length of the cuboid = 2* edge of the cube = 2*6 = 12 cm
Breadth of the cuboid = edge of the cube = 6 cm
Height of the cuboid = edge of the cube = 6 cm
Now, volume of the cuboid = Length*Breadth*Height = 12*6*6 = 432 cm3
