Question

Two cubes of dimensions 3cm x 3cm x 3cm are placed side by side , the length of
resulting cuboid is

Answer 1

Answer:

81 cm³

Step-by-step explanation:

length of the cuboid= 3+3+3=9

breadth of the cuboid= 3

height of the cuboid= 3

the volume of the cuboid= lbh

= 9*3*3

= 81 cm³

Answer 2

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

Note:

The lengths of both the cubes are added,but no change in breadth and height.
