9 cubic units

Step-by-step explanation:

It might help to change the dimensions into half-units (by doubling them).

Width 1 = 2 half-units

Length 1 1/2 = 3 half-units

Height 1 1/2 = 3 half-units

Multiply length x width x height = 18 half-unit cubes = 9 cubic units

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
