To check whether the statements are correct, we need to convert cm to mm.

surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a

1 cm = 10 mm
7 cm = 70 mm

Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²

<span>B. The number representing the surface area would increase.
</span><span>E. The actual surface area would stay the same.</span>

Derive a Boolean function f(x, y, z) that yields a 1 when exactly two of the three input variables are 0.
Rudiy27

Answer:

The notation from analyzing the Karnaugh map is:

F(X,Y,Z) = X'Y'Z + X'Z'Y + Y'Z'X

With logical functions would be:

F(X,Y,Z) = (NOT(X AND Y) AND Z) OR ((NOT Z) AND (X XOR Y))

Step-by-step explanation:

You can reduce the logical function with a Karnaugh map, like the attached, notice the gray coding notation, to assure only one variable change at each cell.
