Given:

The sides of the three cubes are 3 cm, 4 cm, 5 cm.

Formula used:

The volume of cube = side³

The total surface area of cube = 6 × side²

Calculation:

Let the side of the new volume be 'a'.

The volume of the new cube = volume of cube 1 + volume of cube 2 + volume of cube 3

⇒ a³ = 3³ + 4³ + 5³

⇒ a³ = 27 + 64 + 125

⇒ a³ = 216

⇒ a = 6

Total surface area of the new cube

⇒ 6 × a²

⇒ 6 × 6 × 6

⇒ 216 cm²

∴ Total surface area of new cube = 216 cm²

Key Points

• While arranging the parts of the sentence given in options, we have to find  some grammatical or contextual connections  between them , so let’s find out.
• First part of the sentence is  Q  as by looking at all the parts we can make out that sentence cannot start from any other part.
• P  follows Q  because  'significant'  links with  'contribution'  and not with 'that' or 'than'.
• S  follows  P  because 'S' is connected with 'P' by conjunction  'than' .
• Than  indicates  comparison.  As we can see in the sentence comparison is made-  'it is better to live short and contribute' than to 'live long and just wasting time'.
  • For example:
    Seema is more intelligent  than  Geeta.
• Last part will be  R  because  that  logically connect with  life. That  is used when we want to add  something to already mentioned topic.
  • For example:
    She was so angry  that  she didn't ate the dinner.
• Thus, the correct order is  QPSR.

Correct Sentence: 'It is far better to live for a short while and made some significant contribution to the world then spend a long life that is just idled away in gossiping and playing.'

The correct answer is ' In spite of his carelessness towards the project, he got a promotion. '

Key Points

• For a sentence to be correct,  all its parts of speech must be correct  and it  must make complete sense.
• Option 1  is incorrect because the preposition ' on ' is incorrect. It must be replaced by 'towards' .
• Option 2 is incorrect because, in the second part of the sentence, the gender is incorrect. as we're referring to a male, hence it should be ' he got a promotion' instead of ' she got a promotion'.
• Option 3 is incorrect due to incorrect use of punctuation . A comma is used at the end of the subordinate clause (here , In spite of his carelessness towards the project) when it separates from the main clause (here , he got a promotion).
• Hence, option 4 is the most appropriate choice.

The correct answer -  In spite of his carelessness towards the project, he got a promotion.

• जिस समास में उत्तरपद प्रधान हो तथा समास करने के उपरांत विभक्ति (कारक चिन्ह) का लोप हो।
  • जैसे – धर्म का ग्रन्थ = धर्मग्रन्थ, तुलसीदास द्वारा कृत = तुलसीदासकृत।
