ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.
EXPLANATION:
<em>1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell. </em>

Therefore, half of a plant cell's size is 0.000006325 m.
<em>2. We now compare the size of half of the plant cell to the size of the red blood cell.</em>
0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
So in comments section, the legnth is 6 feet width is 5 feet height is 3.5 feet and pool is rectangular prism
volume=legnth times width times height
volume=45
legnth=6
width=5
find height
subsitute
45=6 times 5 height
45=30 time height
divide both sides by 30
1.5=height
answe ris pool is 1.5 feet tall
