The complete outside including the bottom of a wooden 4 inch cube is painted red. the painted cube is then cut into 1 inch cubes . how many of the 1 inch cubes do not have red on any face?

8

Step-by-step explanation:

Only the innermost 8 1-inch cubes would have no red paint on any face.

8 cubes

Step-by-step explanation:

so since all the cubes on the outside have red on it, we need to subtract 56(the total number of cubes on the outside) from 64(the total number of 1 inch cubes that fit in the 4 inch cube)to get 8. or you can just imagine it in your head to see a 2 by 2 by 2 cube  and multiply that  to get 8

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
