Answer:
27
Step-by-step explanation:
Givens
b1 = 13
b2 = ?
h = 6
Area = 120
Formula
Area = (b1 + b2) * h/2 Multiply by 2
2Area = (b1 + b2)*h Divide by h
2Area/h = b1 + b2 Subtract b1 from both sides
2Area/h - b1 = b2
Solution
2*120 / 6 - 13 = b2
40 - 13 = b2
b2 = 27
It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.

Hope this helped.
Answer:
118°
Step-by-step explanation:
Line b is a perpendicular bisector so 90°+28°=118°
Let's say the prisms dimensions were 2×2×2 and you doubled the height 4×2×2.
2×2×2=8 while 4×2×2=16
another example:
4×3×6=144 while 8×3×6=288
therefor it doubles the volume of the prism
