X=2.5
9x=23
Divide both sides by nine and you get 2.555555555555555
So just say 2.5 recurring
The answer to the question in the photo is 21
so, the cube has a <u>cubic hole</u> in the middle.
now, if we nevermind the hole, the volume of the cube, or rectangular prism, is simply the product of its length, width and height, namely 20*20*5, or 2000 cm³.
however, we'll need to subtract the hole from it, and since the hole is another rectangular prism, then its volume is 5*5*5 = 125 cm³.
so if we <u>subtract the volume of the hole</u> from the total volume of the cubic container, what's leftover is just the volume of the <u>cube without the hole</u>, namely
2000 - 125 = 1875 cm³.
<span>Each sphere of ice has a radius of 2cm
</span>one tray makes 6 spheres
<span>What is the total volume of ice the tray can make at one time?
Total volume of each sphere is </span><span>33.51 cm^3
The tray can hold 6 of these at a time
33.5 * 6
201 cm^3 total volume of ice that the tray can make at one time
Written in pi
64
cm^3
Hope this helps :)</span>
