Question

six cubes each of edge 2 cm are joined end to end. find total surface area of resulting cuboid

Answer 1

Six cubes of edge 2 cm are joined end to end.

So, the length of cuboid would become = 6 × 2 = 12 cm

Height and breadth would be the same 2 cm

We know that, total surface area of a cuboid

= 2(lb + bh + lh)

=> 2(12 × 2 + 2 × 2 + 12 × 2)

=> 2(24 + 4 + 24)

=> 2(52)

=> 104 cm²

So your answer is 104 cm²

Answer 2

Answer:

Total surface area of resulting cuboid is $104 \ cm^{2}$ .

Step-by-step explanation:

To find : total surface area of resulting cuboid .

Given : six cubes each of edge $2$ cm are joined end to end .

Solution :

• As per given data we know that ,six cubes each of edge $2$ cm are joined end to end .  
• Length of newly formed cuboid = $6\times 2 = 12$ cm
• Breadth of newly formed cuboid = $2$ cm
• Height of newly formed cuboid =  $2$ cm  
• Now , total surface area of cuboid $= 2 ( lb + bh + hl )$

                                                                 $= 2 ( 12 \times 2+ 2\times 2 + 2\times 12 ) \\\\= 2 ( 24 + 4 + 24 )\\\\=2 (52 )\\\\= 104 \ cm ^{2}$
