S
A
=
96
sq in.
Explanation:
V
=
s
3
64
=
s
3
find the cubic root of each side
3
√
64
=
s
4
=
s
so the side of the cube is 4 cu in.
The surface area of a cube is
S
A
=
n
A
where
S
A
is surface area,
n
is the number of faces, and
A
is the area of one face.
Te area of one face (
A
) is
s
2
so
A
=
16
n
=
6
S
A
=
6
⋅
16
=
96
For a 45 45 90 triangle if the legs are x length then the hyptonuse is x√2
a.
7=x
so hyptonuse=7√2 in
b.
sin(45°)=(√2)/2
c.
not sure what you need SAS for
but, area=1/2 times base times height
base=height=7
area=1/2 times 7 times 7=24.5 square inches
d. not sure, same as above?
Shes got it, she just needs to show the digram for #4 and i can answer them all easily
