The product of the sum of two perfect cubes:
a³ + b³ = (a + b)(a² - ab + b²)
The product of the difference of two perfect cubes:
a³ - b³ = (a - b)(a² + ab + b²)
----------------------------------------------------------------------------------------------------------------
Remember to follow FOIL:
(b^2 + 8)(b^2 - 8)
(b^2)(b^2) = b^4
(b^2)(-8) = -8b^2
(8)(b^2) = 8b^2
(8)(-8) = -64
b^4 - 8b^2 + 8b^2 - 64
Combine like terms:
b^4 (-8b^2 + 8b^2) - 64
b^4 - 64
b^4 - 64 is your answer

Both angles add up to 180.
180-100=80
The missing angle is 80°.
Answer:
The height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
Consider the provided information.
The volume of trapezoidal prism is the area of the cross-section × the length.

Where B is the area of base, H is the length and V is the volume.
The length of the prism is 25.2ft and volume is 1279.152


Hence, the base area is 50.76 ft².
The base is trapezoid.
The area of trapezoid is 
Substitute B=50.76,
in above formula.



Hence, the height of the trapezoidal base is 7.2 ft.
