We are given a six-sided cube. To determine the surface area and the volume of the cube, we need to know the area of one side:
All sides of the cube are squares with side, s. The area of one square is
A = s^2
The surface area of a cube is the sum of all areas of the sides. So
SA = 6 sides * s^2
SA = 6s^2
The volume of the cube is
V = s^3
The volume of the cube represents the total solid area of the cube which includes the space inside the solid.
a = 3, b= - 4 and c = - 4
expand the left side using FOIL
(2x + 1)(ax + b) = 2ax² + 2bx + ax + b = 2ax² + x(2b + a) + b
compare the coefficients of expressions on left and right sides.
compare 2ax² + x(2b +a) + b with 6x² - 5x + c
coefficients of x² terms → 2a = 6 ⇒ a = 3
coefficients of x terms → 2b + a = - 5 → 2b + 3 = - 5 → 2b = - 8 ⇒ b = - 4
constant terms c = b = - 4
AB²=5²+5²+5²=25+25+25=75
AB=5√3≈8.7
Answer:AB≈8.7
