The volume of a cube is 216 ft. What is the length of a side? O A. 6 ft B. 14.7 ft O c. 54 ft O D. 72 ft O E. 108 ft.

A) 6ft.

Step-by-step explanation:

The formula for volume is length × width × height

As you know a cube has all congruent side so if you multiply 6×6×6= 216

which is the volume of the cube

correct

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
