Book cross-section

Front cover 6mm thick
Pages 3.8cm thick altogether
Back cover 6mm thick

The answer is not 20cm !

  • 10a1, Willenhall School
  •  
  • The question says through TO the back cover. This implies that he does not eat the back cover! The answer should be 28.2cm.
  • Transum,
  •  
  • Thanks to all the good people in Year 10 at the Willenhall School for pointing that our. The words 'and including' have now been added to the question.
    Incidently the number of volumes in the Transum Encyclopedia and the thickness of the pages changes each time this page is refreshed so it'll be a different answer next time you visit.
  • Teacher Of 10a1, Willenhall School
  •  
  • My class will be really pleased to see this! This is a great starter for revising decimals and getting students to think functionally. Thanks!
  • Class 8b2, Birkdale High School
  •  
  • Oops - we all need to remember to read the question - even Miss!
    Thanks - we enjoyed this one!
  • Mrs Fairclough's Class, Year 9
  •  
  • Our class want to know how he got to the front cover of the first volume if he didn't eat through it??
  • Miss Williams, Yr 2
  •  
  • This is sooooo good everyone loved this thanks.
  • Emma Wheeler, Maidstone
  •  
  • It is a really good learning programme for me and my class mates we love all your activities.
  • Jenny, Etwall
  •  
  • Hum....how on earth does the worm get to the front cover of volume one,then???Teleportation??
  • George, Gosport
  •  
  • The bookworm was obviously laid as an egg on the front cover of volume one before it was put back in the bookcase.
  • Julie, Perth
  •  
  • Do we have access to the solution to each problem?

    [Transum: The surprising answer and explanation appear below but only for teachers who have signed in. You can find out more about creating a teacher account here.]
  • Stefanie Lehmann,
  •  
  • Surely each book in the middle has got a front and back cover to eat through.

    [Transum: That's right Stefanie. But that's only part of the way to finding the correct answer to this problem]
  • Conyers Maths, Twitter
  •  
  • Bob, Ohio Grade 7
  •  
  • Really cool. All the class enjoyed it.
  • St Ursula's College, Yeppoon, Maths 8+ Class
  •  
  • We think that the answer is wrong because there are gaps between the books. Laney measured the gap and we agreed that it was 3mm making the length of the meal (for 7 books) 36.1cm Thank you.

    [Transum: Good try Maths 8+ but gaps don't count as part of a meal. There's something quite important that you are missing about front and back covers!]

How Not To Be Wrong

How Not To Be Wrong

The maths we learn in school can seem like an abstract set of rules, laid down by the ancients and not to be questioned. In fact, Jordan Ellenberg shows us, maths touches on everything we do, and a little mathematical knowledge reveals the hidden structures that lie beneath the world's messy and chaotic surface. In How Not to be Wrong, Ellenberg explores the mathematician's method of analyzing life, from the everyday to the cosmic, showing us which numbers to defend, which ones to ignore, and when to change the equation entirely. Along the way, he explains calculus in a single page, describes Gödel's theorem using only one-syllable words, and reveals how early you actually need to get to the airport.

Graphic Display Calculator

This handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in the mathematics and science classroom. TI-Nspire technology has been developed through sound classroom research which shows that "linked multiple representation are crucial in development of conceptual understanding and it is feasible only through use of a technology such as TI-Nspire, which provides simultaneous, dynamically linked representations of graphs, equations, data, and verbal explanations, such that a change in one representation is immediately reflected in the others.

For the young people in your life this is a great investment. Bought as a Christmas present but useful for many years to come as the young person turns into an A-level candidate then works their way through university. more... #ad

Math with Bad Drawings

I had been tutoring the wonderful Betsy for five years. When the day came for our last ever session together before the end of her Year 13, I received this beautiful book as a gift of appreciation.

This a very readable book by Ben Orlin. I'm really enjoying the humour in the writing and the drawings are great.

Ben Orlin answers maths' three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that mathematics should belong to everyone. more... #ad
