1)
To find the Surface Area of a cube you do
SA = 6 x
Where [tex a^{2} [/tex] is the side you know.
For this problem you take SA = 6 x
SA = 6 x 4 x 4
SA = 6 x 16
SA = 96

2)
I cannot help you on this, I have never been good with doing trapezoids.

3)
Volume =
Volume = 2
^ 3
Volume = 15
Cosα=adjacent/hypotenuse
In this case you have:
cosα=FE/DF
DF=FE/cosα, we are told that FE=13 and α=34 so
DF=13/cos34
DF≈15.68 which is
DF≈15.7 (to nearest tenth)
