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

OpenStudy (lgbasallote):

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?

I just am confused with what the answer would be?

OpenStudy (lgbasallote):

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?

OpenStudy (anonymous):

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

OpenStudy (lgbasallote):

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

5 years ago
OpenStudy (anonymous):

yes i see that

OpenStudy (lgbasallote):

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

5 years ago
OpenStudy (anonymous):

yes!

OpenStudy (lgbasallote):

so..simplify that...
