The volume of cube is 1000 cubic feet
<em><u>Solution:</u></em>
Given that,
<em><u>The volume of cube is given by formula:</u></em>
![V = s^3](https://tex.z-dn.net/?f=V%20%3D%20s%5E3)
Where,
V is the volume of cube
"s" is the length of one side
<em><u>What is the volume of a cube if the length of a side s is 10 feet</u></em>
Given, s = 10 feet
<em><u>Substitute s = 10 in given formula,</u></em>
![V = 10^3\\\\V = 10 \times 10 \times 10\\\\V = 1000](https://tex.z-dn.net/?f=V%20%3D%2010%5E3%5C%5C%5C%5CV%20%3D%2010%20%5Ctimes%2010%20%5Ctimes%2010%5C%5C%5C%5CV%20%3D%201000)
Thus volume of cube is 1000 cubic feet
Since there are 26 students in Mr. Carson's class, and each kid gets 3 pencils, that means we will multiply 26 and 3, in which we get 78. Now, since boxes of pencils only contain a dozen, which is 12 pencils, we will divide 78 by twelve, in which we get 6.5 boxes. You can't buy half a box, so he will need 7 boxes, since having 6 boxes means that you don't have enough pencils.
Hope this helps!
