Write each number in complex polar form:


When you multiply two exponential expression with the same base (here, that's <em>e</em>), you end up adding the exponents, so that

so the angle of the product <em>zw</em> is 90°.
Answer:
73.5 mm
Step-by-step explanation:
1. Take side length 3.5 mm and calculate the area of one side of the cube.

2. Since cube had six sides, multiply the area of one side by six.
12.25 mm² × 6 = 73.5 mm²
