1/4, find the surface area

144 m^2

Step-by-step explanation:

Base: 8 × 8 = 64

Faces: 5 × 8 = 40 (÷2 ×4 = 80)

Add: 64 + 80 = 144

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.
