Question

three cubes each of Edge 2 cm long are placed together find the total surface area of the cuboid so formed

Answer 1

Answer:

Total surface area of resulting cuboid is $32 \ cm^{2}$ .

Step-by-step explanation:

To find : total surface area of resulting cuboid .

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

Solution :

• As per given data we know that , three cubes each of edge $2$ cm are joined end to end .  
• Length of newly formed cuboid = $3\times 2 = 6$ cm
• Breadth of newly formed cuboid = $2$ cm
• Height of newly formed cuboid =  $2$ cm  
• Now , total surface area of cuboid $= 2 ( lb + bh + hl )$

                                                                 $= 2 ( 3 \times 2+ 2\times 2 + 2\times 3 ) \\\\= 2 ( 6 + 4 + 6 )\\\\=2 (16)\\\\= 32\ cm ^{2}$
