it's almost the same dude..would the markers want to be so fussy just for only 1 toy?

oh, haha true.. btw how much is your box answer?Originally posted by approximately89:it's almost the same dude..would the markers want to be so fussy just for only 1 toy? -
22 boxes(rounded up) ..if i'am not wrong..i used 423 tiles divided by 20 tiles..
-
alamak i got 22.25 box.. round up leh.. coz u cant possibly forsake the 0.25 box of tiles..

Cannot round up... how you account for extra metal for the last toy?Originally posted by approximately89:answer for the numbers of toys to be made
vol.of cone+hemisphere(toy)= (1/3 x pi x 5^2 x 12) + (2/3 x pi x 5^3)
=575.9 cm^3(round up to 576cm^3)
vol. of metal cylinder= pi x (150)^2 x 200
= 14137166.9cm^3 (round up to 14137167cm^3)
therefore : numbers of toys made = 14137167cm^3 divide 576cm^3
= 24543.69 (round up to 24544 toys)
Nevermind... at most minus 1 mark...
I converted to m^2... even worse...

haha..like what i said just now..22, 23 boxes are ok..not to the extent of 30-40 boxes
