I just printed out the Maths Test paper for my son for the 2013 st olaves exam.
Question 25 A & B asks about volume and cubes.
The answer for question 25 B says it is 12 but I cannot see how. I have it as 13. Is this a mistake or can I not work this out correctly.
The question is how many cubes which are 3x3x3cm (27cm) will fit into a box 6x10x6cm (360cm)
360 / 27 = 13.3 not 12
Where am I going wrong?
I could be wrong because maths is not my thing, but I think it is more about the shape of the boxes rather than the volume. i.e, I think the first box would fit in the second box in two columns of two (4 boxes) x three rows high (3 boxes), giving you a total of 12.
I think that's right and I hope I've explained my muddled thinking!
