Answer:
87.5% of the cube's original volume has melted away.
Step-by-step explanation:
So, you will need to calculate the volume of the initial ice cube, as well as the melted ice cube to find the percentage of the volume.
Original Cube
V=l³
V=2³
V=8
Melted Cube
V=1³
V=1
Next, we need to find how much melted by subtracting the new from the old.
8-1=7
Next, we need to find the percentage that melted by dividing the volume that melted from the original volume. Then multiply the decimal by 100 to get the percentage value.
7/8=0.875
0.875×100=87.5
87.5% of the cube's original volume has melted away.
