The average of 6 numbers is 7. When a 7th number is addedThe average of all numbers is 0. What is the seventh number?

Katena32 [7]

-- The average of 6 numbers is 7.
    So those 6 numbers must add up to 42.

-- If one more number results in an average of zero,
   the new number must be -42 .
   Then all 7 numbers add up to zero.

A candy store called "Sugar" built a giant sugar cube out of wood to hang above the entrance to their store. It took 545454 feet

DedPeter [7]

Answer:

<em>The volume inside the giant sugar cube is 27 cubic feet.</em>

Step-by-step explanation:

It took 54 feet² of material to build the giant sugar cube. That means, the total surface area of the cube is 54 feet²

<u>Formula for surface area of a cube</u> is: $S= 6a^2$ , where $a$ is the length of each edge of the cube.

So, we will get.........

$6a^2=54\\ \\ a^2= \frac{54}{6}=9 \\ \\a= \sqrt{9}= 3$

Now, <u>the volume of the cube will be</u>: $V= a^3= (3)^3 = 27$ feet³

Thus, the volume inside the giant sugar cube is 27 cubic feet.
