The length of each edge of a cube is x centimeter if x is an integer why can't the volume of the cube equal 15 cm squared

Because cubes feature only certain values:

1^3 = 3

2^3 = 8

3^3 = 27

There is no x, x an integer, for which x^3 is = 15 cm^3.

Note well: the units of volume in this case are cm^3, not cm^2.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

b is the right answer
