The surface area of a cube is 600 cm2. What is the area of one face of this cube?

Since it is a cube that would mean that it has 6 faces and we know of the surface area so we can simply divide by \(\Large{6}\) to get our answer... \(\Large{600 \div 6 = area~of~one~side}\)

KjSaif (kjsaif):

i think 10

KjSaif (kjsaif):

i mean 100

KjSaif (kjsaif):

but i'm the one who needs help ('-')

@563blackghost

563blackghost (563blackghost):

oooo im so sorry....i feel so bad

KjSaif (kjsaif):

XD it's cool

563blackghost (563blackghost):

Well it is not 10 because \(\Large{6 \times 10=60}\) which is not equal to \(\Large{600}\) So if we did it with your second guess which is \(\Large{100}\) then it will equal \(\Large{600}\)....So it is \(\LARGE\color{red}{100}\)

OpenStudy (khalid3166):

i think 10 to though look at this

OpenStudy (khalid3166):

but you seem right though

OpenStudy (khalid3166):

i got this from google

563blackghost (563blackghost):

@Khalid3166 That is the length not the area if we do multiply the length by itself it will equal the area of one side.... \(\Large{(length=10) \times (length=10)=(area=100)}\)

OpenStudy (khalid3166):

OH -_-

KjSaif (kjsaif):

ok so 100 right?

563blackghost (563blackghost):

Correct ^^
