All you gotta do is calculate its volume by using the formula
LengthXWidthXHeightand then divide by 2
<u><em>Density= Mass divided by Volume</em></u>, but you're trying to find Volume so you apply Algebra and get <u><em>Volume= Mass divided by Volume.</em></u>
Volume= 0.5592841163 [kg/m (power to the 3)]
You should round it up
Answer:
-2755 plants
-40mg is left.
Step-by-step explanation:
Given the fertilizer amount is 1.08kg, and the amount per plant per year is (4*98mg):
#convert the weight of the fertilizer into grams then divide by quantity per plant to determine number of plants;
![Number \ of \ plants=\frac{Fertilizer \ Amount}{Quantity \ per \ plant}\\\\=\frac{1.08\times 1000000}{98\ mg\times 4}\\\\=2755.1\approx2755](https://tex.z-dn.net/?f=Number%20%5C%20of%20%5C%20plants%3D%5Cfrac%7BFertilizer%20%5C%20Amount%7D%7BQuantity%20%5C%20per%20%5C%20plant%7D%5C%5C%5C%5C%3D%5Cfrac%7B1.08%5Ctimes%201000000%7D%7B98%5C%20mg%5Ctimes%204%7D%5C%5C%5C%5C%3D2755.1%5Capprox2755)
-There are 2755 plants planted.
-We subtract the fertilizer used from the total to find what is left:
![Left=Total -Used\\\\=1080000\ mg-(2755\times98\times4)\\\\=40\ mg](https://tex.z-dn.net/?f=Left%3DTotal%20-Used%5C%5C%5C%5C%3D1080000%5C%20mg-%282755%5Ctimes98%5Ctimes4%29%5C%5C%5C%5C%3D40%5C%20mg)
Hence, 40 mg of the fertilizer is left over.
