Question

If two cubes of dimensions 3 cm by 3 cm by 3 cm are placed side by side, then the resulting dimension of the cuboid is length (l), breadth (b) and height (h). Find the value of l+b+h (in cm).​

___

Answer 1

When we put the cube side by side, then the lengths of both the cubes are added, but there will be no change in the breadth and height of the cube.

Length (l) = (3+3)=6 cm.
Breadth (b) = 3 cm.
Height (h) = 3 cm.
Hence, l+b+h = 6+3+3 = 12 cm
