. If three cuboids of dimensions 4 cm by 2 cm by 3 cm are placed side by side, then the dimensions of the resulting cuboid would be


(a) 4cm x 2cm x 3cm.       

(b) 12cm x 2cm x 3cm.

(c) 12cm x 6cm x 3cm.     

(d) 12cm x 6cm x 9cm.

Best Answer

(b)

Explanation:

The dimensions of the resulting figure are

Length = 4cm + 4cm + 4cm = 12cm     (combine the length of three cuboids)

Breadth = 2cm = 2cm                 

Height = 3cm                              (Breadth and height will be same for new cuboid)

Now, the new dimensions of the resulting cuboid = 12cm x 2cm x 3cm.
