Answer:
20 cm
Step-by-step explanation:
A cube has 6 faces. Two of the faces are bases. The other four faces are lateral faces.
Let the area of 1 face = x
4x = 1600 cm^2
x = 400 cm^2
Since the area of 1 face is 400 cm^2, then the side length is sqrt(400 cm^2) = 20 cm
Answer: 20 cm
The answer is D, 4/3 x 3.14 x 2^3
<span>y=1/2x+7, slope is 1/2
</span><span>perpendicular so slope is opposite and reciprocal
</span>slope = -2
<span>passes through the point (6,2)
</span>y - 2 = -2(x - 6)
y - 2 = -2x + 12
y = -2x + 14
answer
equation y = -2x + 14
