Question

HELP ME PLEASE!!!!

How would I calculate the volume of the rectangular prism in cubic centimetres? The dimensions are 25mm length, 21mm width and height is 9mm. Originally the units were in millimetres.

Answer 1

V = lwh

Answer 2

V = (25)(21)(9)

Answer 3

got it
so times

Answer 4

you have to multiply?

Answer 5

yes

Answer 6

okay so
4725

Answer 7

V = 4725 mm ^3 but then it asks you in centimeters

Answer 8

yea it does

Answer 9

so you have to convert from mm^3 to cm^3

Answer 10

so i write 4725cm3

Answer 11

no

Answer 12

then

Answer 13

because it is 4725mm^3

Answer 14

to convert 4725 from mm to cm. You have to divide it by 10

Answer 15

Volume = length*width* height
V = 25*21*9
then your result multiply by .001 to get cm^3

Answer 16

ohh

Answer 17

V=472.5 cm^3

Answer 18

so okay

Answer 19

it is because 10mm = 1cm so you divide it by 10

Answer 20

i understand

Answer 21

And how do I calculate the capacity

Answer 22

got any idea?

Answer 23

1sec

Answer 24

How would I calculate the capacity of the rectangular prism in cubic centimetres? The dimensions are 25mm length, 21mm width and height is 9mm. In millimetres

Answer 25

no problem

Answer 26

You convert it to meters ^3 and multiply it by 1000 because 1m^3 = 1000Liters

Answer 27

but what do i convert

Answer 28

the answer in cm that you received to meters

Answer 29

472.5cm3 in metres and then multiply by a 1000

Answer 30

I made a mistake converting mm^3 to cm^3. Instead of diving it by 10. you divide it by 1000

Answer 31

so V=4725mm^3 ---> 4725/1000 = 4.725cm^3

Answer 32

so u talking about the volume

Answer 33

okay

Answer 34

yes

Answer 35

got it

Answer 36

okay so now the capacity

Answer 37

So now to get the capacity, first we need to convert the volume to meters.

Answer 38

meters^3 *

Answer 39

yep

Answer 40

4.725/1000000

Answer 41

0.000004725

Answer 42

is that metres

Answer 43

meter ^3

Answer 44

and then now to litres which is 0.0047250L right?

Answer 45

0.004725L yes

Answer 46

and thats the answer

Answer 47

yup

Answer 48

so altogether it is 4.725/1000000=0.000004725- this is metres

Answer 49

what do i do to get litres

Answer 50

1m^3 = 1000liter

Answer 51

so multiply

Answer 52

you have to convert it to meters^3 to get liters so multiply it by 1000

Answer 53

okay

Answer 54

Yes, first you have to find the volume. Then if you they ask for the capacity, convert it to m^3 and multiply it by 1000.

Answer 55

got it

Answer 56

how do u know all this stuff?

Answer 57

You can understand all the concepts very easily when you are in high lvl of math.

Answer 58

I'm in year 8

Answer 59

so u mean in like year 9,10,11 or 12

Answer 60

I had Calculus BC in High School 12th(Senior)

Answer 61

If you get to hit Calculus. Then Geometry/Algebra become very easy because you are constantly using it in Calculus in different ways.

Answer 62
