Tentang Kubus

15 Juni 09

Kubus adalah bangun ruang yang memiliki beberapa keunikan dan menurut saya adalah bangun ruang yang spesial dibandingkan dengan bangun ruang yang lainnya. Bangun ruang ini juga bangun ruang yang saya kenal pertama waktu SD dulu dan sangat fasih dengan rumus-rumus yang melekat padanya.
Unsur-unsur dalam kubus:

  • 6 sisi kongruen berbentuk persegi
  • 12 rusuk
  • 8 titik sudut

Keunikan dalam kubus:

  • semua diagonal ruangnya bertemu di pusat bangun tersebut
  • sebuah kubus yang memiliki rusuk a cm maka panjang diagonal sisinya adalah aV2 cm ( V=akar)  dan panjang diagonal ruang adalah aV3 cm.

Rumus-rumus dalam kubus:

  • luas permukaan = 6 x a² (a = rusuk kubus)
  • volume = a³

Demikian tadi sedikit ulasan tentang kubus semoga bisa kasih sedikit pengetahuan buat kalian.

  3. The funny thing is, you never had a social life before you started dating.
    For whatever reason should your partner be separated from you for almost a whole year, it’s
    important that you bridge that gap by traveling to be with them
    at least once every few months. How much will an online medical coding program cost.

    ‘ Single wall cup in white, plain colours and logo prints.

    Not only are they providing gourmet coffee with a healthy twist they
    are delivering it in single serving stix that make it
    convenient, easy to make, and easy to share. Right now, there is a lot
    of hype and noise surrounding Javita, because it’s in pre-launch, and the ‘Reserve
    Your Cup’ marketing campaign seems to have spread virally.

    Although a part of life in the traditional stories we know, Egyptian jewelry (Rosalinda) bears evidence for style, class and glamor in today’s age.
    While buying Gold Jewellery, look for hallmark or trademark apart from the karat marking.
    Other features such as design and patterns can also be used.

    Remember all of the tips I mentioned above and be sure to always, always,
    make sure the site you are buying from is secure, offers a contact option clearly on every page,
    and of course make sure the prices are right.
    You need to make sure that you will have enough space to accommodate everything in your jewelry collection as well as some if not all of the jewelries that will most likely to collect in the near future.
    Jewelry boxes have been around for many years and have proven to become verry common
    now a days, how ever years ago they was primarily used for storing
    important documents cause not many people had jewelry collections
    like they do now a days.

  11. A large number of people are facing great difficulties to fulfill their requirement.
    Most lenders have gone back to a more conservative 60 –
    65% LTV. Many years ago, My Personal Loan took the initiative to reduce
    the complexities of personal loan application procedure; they have
    reduced unnecessary paper-work, improved on the company’s operation process and also leverage
    on information system to automate some of the manual process.

    Twist your upper body to your left and back through to the center and then next to your right.
    Ideally you are drinking just water or maybe freshly squeezed
    juices from fruit or vegetables. Some people are self-motivated, but everyone can use encouragement and
    guidance from time to time.

  14. I’ve been surfing online greater than 3 hours lately, but I never
    found any attention-grabbing article like yours. It is lovely value sufficient for me.
    In my opinion, if all web owners and bloggers made just right
    content as you probably did, the net will likely be
    much more useful than ever before.

    Internet users all over the world can easily distinguish between an article written for humans and write-ups that are produced for the benefit of search engines. Therefore, given that marketing is so to speak at the core of any business, if you want to sell well, you have to advertise well, and you can do this on the internet, given it is the best means to help you achieve your goals to this effect due to its massive exposure and incessant expansion. Even so, I believe Kris Roadruck made a lot of good sense in his comment when he explained that, “Doing [the redirect] can certainly help would-be linkers know which is the appropriate address to make use of when linking.

    Many of them are rife with spelling issues and I to find it very bothersome to tell
    the reality however I will definitely come back again.

    Search engine optimisation has changed a lot recently, because the
    work is technical it is best suited for workers who have
    studied the industry and have practical experience, this
    can be quite rare with SEO professionals though

    I have observed that in the world of today, video games are definitely the latest trend with children of all ages. Periodically it may be not possible to drag your son or daughter away from the games. If you want the very best of both worlds, there are several educational video games for kids. Great post.
