Working out cubic volume
 

How embarassing.

Ok, so I'm shipping some stuff by sea and the freight co charge by cubic metres. Below are the dimensions of each item as given to me by the supplier's warehouse.

I will have 2 of each:

Length: 0.32m
Height: 0.20m
Width: 0.28m

Length: 0.30m
Height: 0.27m
Width: 0.27m

My math isn't what it used to be, apparently.

Re: Working out cubic volume
 

You multiply the length by the width by the height of each item to get the volumne.Then add the results together to get the total.

Thats what I did but kept getting negative values.

Site is playing up for me, but I'll try after dinner!

Thanks

Regards

Stupid.

Box 1 is 0.1792
Box 2 is 0.2187

If you have two of each you double those numbers and add the result together for the total.

Re: Working out cubic volume
 

1.792m(cubed) + 2.187m(cubed)

3.979m(cubed)

I worked in cm for the values you gave me inm(cubed), to find a value in cm(cubed), then to get back to m(cubed) you have to divide by (100x100=10000).

Its because the values are >1, they make funny figures, so you have to go up from m(cubed) to cm(cubed) then divide back down.

I think thats right, but wait for someone more knowledgable than me to tell you.

I think I am possibly wrong looking at BB's answer!

Re: Working out cubic volume
 

Surely volume is simply length x breadth x height

Therefore box 1:

0.32 x 0.2 x 0.28 = 0.01792m^3

box 2:

0.3 x 0.27 x 0.27 = 0.02187m^3


Hopefully we agree on that... seeing as im studying engineering and hopefully not making schoolboy errors!

Yet i find it interesting that there are 3 sets of answers, all the same numbers, but factors of 10 different!

Re: Working out cubic volume
 

Are you shipping them all in separate packages? Placing them all in the same box will leave room left over so the total will be slightly more than the individual boxes combined

That said, the volume of the first item is:

0.32 x 0.20 x 0.28 = 0.01792 cubic metres

Item two:

0.30 x 0.27 x 0.27 = 0.02187 cubic metres

Double the values for two of the same item, add the results for the total

simples...

Re: Working out cubic volume
 

Box 1 = 0.32m*0.2m*0.28m = 0.01792m^3
Box 2 = 0.3m*0.27m*0.27m = 0.02187m^3

2 Of each box = (2*0.01792)+(2*0.02187) = 0.08m^3 (or 0.07958 if you want to be accurate).

Edit: Factors of 10 catch loads of people out.
