Best ResponseYou've already chosen the best response.0I don't know, how would you do that?

Best ResponseYou've already chosen the best response.0you would multiply width by length, no?

Best ResponseYou've already chosen the best response.0Okay, and how do I figure out the width or the length? It only says "4x5" underneath the cube.

Best ResponseYou've already chosen the best response.0I don't know if that's right. If you say so. I don't know that much about this topic. So what would the width or length be in this situation?

Best ResponseYou've already chosen the best response.0to figure an area of a rectangular region, you multiply it's length by it's width

Best ResponseYou've already chosen the best response.0Well myko just told me how, but I do not know the width or length is of this rectangle.

Best ResponseYou've already chosen the best response.0so , imagine you have a square (length = width) dw:1354440386801:dw

Best ResponseYou've already chosen the best response.0this is, actualy, one of the faces of the cube. To find total surface area, just count how many faces it has.

Best ResponseYou've already chosen the best response.0I'm assuming it has 6 faces, right?

myko

Best ResponseYou've already chosen the best response.0you right, so total surface area will be 6 times the area of one of the faces

Best ResponseYou've already chosen the best response.1The definition of area reads: area: The area of a region is the number of square units it contains.

Best ResponseYou've already chosen the best response.1In this question you can not calculate a numerical answer because you don't know what the value of x is. You can only give the equations: surface area = 6(4x5)^2 volume = (4x5)^3
