hi maggie

nottim · Answer

sorry, this questions is worded confusingly. Is this cm^3, or $$cm^3$$

anonymous · Answer

no

lgbasallote · Answer

lol what is the purpose of a foot is 30 cm lol...no conversion is neeeded anyway

nottim · Answer

i was wondering about that too. a red herring?

nottim · Answer

i just wanna say its 3L, but I can't really explain clearly why, nor does it sound  correct

A cube 10 cm on edge can hold a liter of water.  A foot is about 30 cm.  How many liters of water can a cube 30 cm on edge hold?

anonymous · Answer

It is not 3L

nottim · Answer

i see the question. what deos "on edge" mean?

lgbasallote · Answer

well anyway..volume = side x side x side

for the first problem

volume = 10 x 10 x 10
volume = 1000 cm^3
volume = 1L

therefore

1 L = 1000xm^3

what was the purpose of repeating the question?

lgbasallote · Answer

do you understand what i wrote there @tdawgisinthehouse

anonymous · Answer

no im sorry

anonymous · Answer

I just am confused with what the answer would be?

lgbasallote · Answer

volume of a cube is side x side x side

in your first sentence it says that when the cube has 10 cm side the volume is 1 L. we replace the formula i wrote

1L = 10 cm x 10 cm x 10 cm

got it?

anonymous · Answer

yes...but i still do not see the clear answer there

lgbasallote · Answer

we'll get there...if we simplify what i wrote

1 L = 1000 cm^3

got it?

anonymous · Answer

yes i see that

lgbasallote · Answer

now in the second problem...

volume = side x side x side

volume = 30 cm x 30 cm x 30 cm

got it?

anonymous · Answer

yes!

lgbasallote · Answer

so..simplify that...

anonymous · Answer

27,000?

anonymous · Answer

is the answer 27 liters?

lgbasallote · Answer

YES!

anonymous · Answer

lgbasallote · Answer

anonymous · Answer

it is related
