Step-by-step explanation:
Answer:
one cubes: 73.5 ft²
two cubes: 147 ft²
Step-by-step explanation:
Using plastic to construct a cube means finding the surface area of the figure. The general formula for the surface area of a cube is:
SA = 6s², where 's' is the measure of one side.
Since one side is 3.5 feet:
SA = 6(3.5)² = 73.5 ft² per cube
Two cubes: 73.5 x 2 = 147 ft²
6x^2 +30x - 36
6( x^2 +5x -6)
6(x^2 -x+6x-6)
6[ x(x-1) 6(x-1)]
(x-1) (x+6)
