The volume of water that the restaurant saves is; 12.87 cm³
<h3>How to find the Volume of a Sphere?</h3>
Volume of a cube = x³
where x is side length
Thus;
Volume of Ice cube with a side length of 3 cm is;
V_ice cube = 3³ = 27 cm³
Side length is now halved and so;
New side length = 3/2 = 1.5 cm
Thus;
New Sphere volume = ⁴/₃πr³
New Sphere volume = ⁴/₃π * 1.5³
New Sphere volume = 14.13 cm³
Thus;
Amount of water saved = 27 - 14.13 = 12.87 cm³

To find the surface area, you will use the formula area equals length times width to find the areas of all six shapes.
4×11, 4×5, and 11×5 are the three different areas shown. There are two of each, so 44×2, 20×2, and 55×2. 88+40+110=238 square mm.
238 square mm is the surface area.
I'm sure the answer is 2 and 1/4. it has to be a positive and the marker is over 2 so...yeah
