Ajewelry box is shaped like a cube. one side of the box is 6 and 1/2 inches long. what’s is the volume of the jewelry box.

217.5 or 217 1/2

Step-by-step explanation:

C

Step-by-step explanation: The answer is C because the volume formula for a cube is V=lwh. V=6.5 times 6.5 times 6.5, or V=6.5^3.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
