<em>Comment on the question</em>
The way the question is worded, "A" can be any value less than 68.1, down to -∞. The question does does not require the A-B range to be symmetrical.
Total area of the cube = 6s² (s=side)
96 = 6s²
s² = 96 ÷ 6
s² = 16
s = √16
s = 4 in
V = s³
V = 4³
V = 64 in³
Hi there!
To solve this problem, we need to simplify.
(x + 10) + (3x + 2) = 180
x + 3x + 10 + 2 = 180
We combine like terms first:
4x + 12 = 180
And isolate x.
4x = 168
Now, we divide both sides of the equation by 4 to solve for x.
x = 168 ÷ 4
x = 42
Hope this helps!
