mokeira · Answer

first find the length of one side.
because the sides are all equal,
$$v=(side) \times (side) \times (side)$$
so basically
$$v=(side)^{3}$$
so
$$1331=(side)^{3}$$
to get one side, find the cube root
$$side=\sqrt[3]{1331} = 11$$
so surface area will be
$$(11 \times 11)$$
for one face. but there are 6 faces so multiply your answer by 6

Can you help me with this? 
Find the area and perimeter of the polygon with vertices A( 3, 0), B(3, 4), C(5, 1), and D(-1,-3 ).
a. area = 26 units ; perimeter = units
b. area = 13 units ; perimeter = units
c. area = 13 units ; perimeter = units
d. area = 26 units ; perimeter = units

It is area of one face..but there are 6 faces @jhonyy9

yes sotty i not have learned your next lines

mokeira · Answer

first plot it to see what shape it is

kinda like this shape 
@Mokeira

mokeira · Answer

thats not right..what are the coordinates of D?

fionacndg · Answer

-1, -3
@Mokeira

mokeira · Answer

have you plotted D well?

fionacndg · Answer

no

mokeira · Answer

did you get something like mine

fionacndg · Answer

now i did get something that looks more like yours

mokeira · Answer

yeah... divide it insuch a way that you get two triangles...then work with those to make things easier...I have to go but when i get back i will check in on you

fionacndg · Answer

oh gosh. okay well I don't know if i can do this I have no idea how to do this at all... thanks for the help anyway
