Use the formula: A= (a+b/2)h
A=(8+5/2)6
A=39
The answer is the light blue box, 39cm^2

The slope perpendicular to 1/4 or .25 is 4.
Then you would use point slope form to write the equation.
Then you could simiplify the equation to y=4x+32.
Answer:
Surface area of a square prism = 4 × (s × h) = 4sh, where, s is the length of the side of the square and h is the height of the square prism.
Answer:
80
Step-by-step explanation:
SIMP - lifiy the equation: (see what I did there :D)
4xy^2 = 4(5)(2^2) = 80
ANSWER: 80
Use the volume formula
V=l•w•h
Soo…
V=8•12•2 and that would be your answer
