errggh - Maths problem

[Piercy]

Hi

I have a space of 60cm x 91cm x 10000cm how much of this space would 3 cubic meters take up?

On going problems with next door - long and boring and I'm hating that this matter is taking up a Bank Holiday Monday without trying to work maths out.

Is there a formula to this - help me please - thanks

I think your space is 5.46 cubic metres, so 3 cubic metres would take up slightly over half. Subject to ratification.

Turn it into the same units for both measurements.

So 3cubic m is 3,000,000 cm cubed, I think.

But your space is 60 x 91 x 10,000 = 54,600,000

Take the first away from the second and you have 51,600,000?

I think.

Hmmm. Maybe not, then!

Co vetting them in meters would give
0.6x0.91x100= 54.6 cubic meters. Is there an extra 0 in that last measurement? 100m seems like a lot for a house.

Converting

Mine would come out at 51.6 metres cubed!

Might be easier to work in m:

0.60 x 0.91 x 100 = 54.6 cubic metres. (which agrees with BSJohnson).

Subtract 3, leaving 51.6 cubic metres.

Your space is 0.6m x 0.91m × 100m (are you sure about this one???)
That makes 54.6m^3

3m^3 is a tiny amount of the total space.

BUT if the shapes aren't changeable, it won't fit in - if your 3m^3 is 1mx1mx3m its never goingbto fir in a space that is 0.6m x 0.9m

Are the original dimensions correct? you are describing something like a long (100 metres) but fairly narrow and shallow trench.

So, we're agreed on the maths, but all curious as to 3 m^3 of what going into what space?

5.46 cubic metres - 3 cubic metres = 2.46 cubic metres. But it depends on the measurements of the 3 cubic metre shape as to whether it fits

60cm x 91cm x 10000cm

You can guesstimate it

You have a cube of just over half a metre x just under a metre times a 100 metres

Have you got that last number right or is there and extra 0?

So you have about 50 cubic metres

Try that in a calculator:www.ginifab.com/feeds/cbm/cubic_meter_calculator.html

pudcat - you've answered the question for 60 x 91 x 1000 which is not what the OP asked, although it's possible OP typed an extra zero.

You could be pedantic and answer "3 cubic metres". If the question is what percentage of space then:

30 ÷ 54.6 × 100 = 54.945%

If it is 1m 1m 3m = 3 cubic metres it wont fit. You need to know exact dimensions of it

But that isn't right if the number of 0s in the OP is correct, it'd be about 5%

Top marks to Pudcat! So bleeding obvious! And there we all were being clever about the 0s

TooTrue - excellent point about reading the question, but you've made a slip, it's

3 / 54.6 x 100 = 5.49%

pudcat - you've answered the question for 60 x 91 x 1000 which is not what the OP asked,
sorry was a typo - decimal point in wrong place

If anyone wants a real maths problem, there's one in the Guardian today (Alex Bellos's fortnightly puzzle):

www.theguardian.com/science/2018/may/07/can-you-solve-it-im-a-mathematician-get-me-out-of-here

My kids are taught to 'guesstimate' first, then tighten the answer up. I was dubious at first (I was schooled in the 70s) but now, I dunno...

So 60 x 91 x 10000 is roughly 50x100x10000 = 500,00,000 (90% correct).
Or even better if you convert to meters first: 0.5m x 1m x 100m = 50 cubic metres.
The next step is to do the sum properly, this time with "roughly 50" in mind.
I was only sniffy about it until I realised I do this myself all of the time.

Fair point DadDadDad. I realised shortly after posting.

wow - how are people able to do this and I've been left scratching my head!?!?!

To give you a bit of an overview it is a weird shape as DH and I have dispute with neighbour and an adjoining piece of land so it is 60 cm wide x 90 cm high x 10 m long

Its a log storage area - its a very long boring story - and the man needs to get a life but is retired and sees us as sport to make our lives a misery and fill in his time!!

My little boy has picked me flowers this morning as he knows I'm having to write a response to the neighbour and I would much rather be out playing with him - bless him xx

And thank you to guys n girls with great mathematical minds!!

Aha! So, OP, your original information was incorrect, as some of us suspected. If you are saying 10m then the volume is 5.46 cu metres, so 3 cu metres will leave you 2.46 cu metres.

Ok. If it's 10m long, the answer is about half the space.
The numbers you put in to start with make it 100m long.
