Answer:
1
Step-by-step explanation:
You only need two points to find the slope.
Let's use (1,7) and (2,8).
The formula for slope is (y2-y1)/(x2-x1)
Let's plug the values in:
(8-7)/(2-1) = 1.
So, the slope is 1.
Since the length of each side of cube is s.
Volume of a cube = s³ = s*s*s
Since length of side = 6cm
Volume = 6³ = 6*6*6 = 216
Volume = 216 cm³
Option A.
