No, the table does not represent a linear function
Step-by-step explanation
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. it has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y
Step 1
graph

so, the graph does not represent a linear function , Also
the volume of a cube is given by

the exponent of the function is 3, and for a linear function the exponent in the varialbe must be 1,
