Question

STOP! Which of the following is not a step in the conversion of 37 L to dam3?

Answer 1

hero, be my hero :)

Answer 2

So the liters are not cubed?

Answer 3

no :/

Answer 4

Okay, no worries

Answer 5

I know how to convert it, but I'm not sure which one doesn't belong

Answer 6

errrrrr :(

Answer 7

Answer 8

Well, there is a way to figure it out

Answer 9

how?

Answer 10

Hang on a sec

Answer 11

Okay, basically in the given answers, the numerator and denominators are supposed to be equal to each other.

Answer 12

In one of those answer choices, the numerator is not equal to the denominator. Find out which one is not equal.

Answer 13

how do you do that?

Answer 14

By being familiar with the prefixes

Answer 15

d?

Answer 16

You're guessing

Answer 17

liters are a measurement of what

a) length

b) area

c) volume

???

Answer 18

volume

Answer 19

good, dam^3 (read as "cubic dekameters") are a measurement of what?

a) length

b) area

c) volume

???

Answer 20

length

Answer 21

no

Answer 22

the cubic is a hint

Answer 23

area

Answer 24

when you have a cube, it's 3D right?

Answer 25

yes

Answer 26

as compared to a 2D square

Answer 27

so any measurement with the word "cubic" in it (like cubic inches) measures volume

Answer 28

oh ok :(

Answer 29

so you're converting from one volume measure (liters) to another (cubic dekameters)

Answer 30

when doing volume measurement conversions, you involve exponents of 3 (to represent the idea that you convert for each dimension)

Answer 31

okay

Answer 32

so of the choices above, which looks out of place (based off what I just told you)?

Answer 33

c! lol

Answer 34

good, that is missing the exponent of 3 over everything to make that a proper volume conversion multiplier

Answer 35

haha duh! thank you :)))))

Answer 36

Which of the following is the smallest volume?

2500 mL

30 cm3

2.0 x 10-1 L

25 m3

Answer 37

b?

Answer 38

Convert everything to the same volume (I'm converting everything to liters)

2500 mL = 2.5 L

30 cm^3 = 0.03 L

2.0 x 10^-1 L = 0.2 L

25 m^3 = 25000 L

Answer 39

okay, so c?

Answer 40

0.2 is the smallest?

Answer 41

0.2 L*
