Answer:
The maximum volume the cube could have is 729 cubic inches
Step-by-step explanation:
The total surface area of the cube equals the total area of material used.
Let A = total surface area of cube = 6L² where L = length of side of cube
Since A = total area of material used, A = 486 in²
So 486 in² = 6L²
L = √(486 in²/6)
= √81 in²
= 9 in
The volume of the cube V = L³ where L = length of side of cube
So, V = (9 in)³
= 729 in³
So the maximum volume the cube could have is 729 cubic inches.

Hopefully this is right, basically you are just turning negatives into positives I think.
Answer: 0
Step-by-step explanation:
We first convert -0.33 to fraction so they can both be in fraction and have the same denominator
It converts to -1/3
Therefore, there is zero rational number between-1/3 and -1/3
Since you're only given the one vector, I assume you're supposed to find the magnitude of <em>v</em>, or ||<em>v</em>||, using the dot product.
We have
<em>v</em> • <em>v</em> = (-2, -1) • (-2, -1) = (-2)² + (-1)² = 5
so that
||<em>v</em>|| = √(<em>v</em> • <em>v</em>) = √(5)
and the answer is C.
