Question

WILL MEDAL FOR HELP!!!
a cubical box with the dimensions 3 x 3 x 2 is melted into another cube whose width is 15. Find the length and height of the cube formed if l=h. formula for volume is w x l x h
Width
Length
Height

Answer 1

I think you have to multiply the dimensions of the first box by 5. So 3*5, 3*5 and 2*5. So your dimensions are 15*15*10 and you multiply those together. So the length and height are 15 and 10. Im not sure if this is right though....

Answer 2

You need to find the volume of the first box. Wjhat will that be?

Answer 3

i don't think thats right. the volume has to stay the same.

Answer 4

and the volume would be 18

Answer 5

for the 1st one

Answer 6

Me? or nelsonjedi

Answer 7

Answer 8

well there isn't a whole lot of info

Answer 9

is there suppose to be a specific pattern to use?

Answer 10

OK now you have the volume of the first box is 18. We are melting it into a second box so the volume of the first box needs to equal the volume of the second box. How would you figure that out>

Answer 11

thats what i'm having trouble on. it would be 18= 15 x l x h but idk what to do next.

Answer 12

well 15 is the width and u cant really get 18 as the volume unless u use decimals maybe

Answer 13

or fractions as your 2 dimensions

Answer 14

i've tried dividing 18 by 15 but that didn't work right.

Answer 15

Jenn is right. Now we do we know about l and h for the second box?

Answer 16

try fractions or decimals

Answer 17

Divide both sides of the equation by 15 and what do you have?

Answer 18

15* 1/5*6???

Answer 19

1.2= l x h

Answer 20

i think i got it

Answer 21

yeah. but if you divide 1.2 by 2 you get .6 and if you then do the equation out it comes out as 5.4

Answer 22

when it should come out to 18

Answer 23

Sorry if l and h are equal the it would be the same as l^2 or h^2

Answer 24

yeah.

Answer 25

do i need the sqrt of 1.2 then?

Answer 26

l and h might be 1/3 and 6 unless there are no fractions wanted

Answer 27

No sqaure root of 1.2 works

Answer 28

Candy the problem states that l and h are equal

Answer 29

YAY!!! thanks guys so much! :)

Answer 30

Welsome :-)

Answer 31

where does it state that

Answer 32

it just say sto find l and h

Answer 33

it says find the length height of the cube formed if l=h
