Answer:
81 cm^2
Step-by-step explanation:
Side = perimeter / 4 = 36/4 = 9 cm
area = side^2 = 9^2 = 81 cm^2
Let the missing number be x
r= x/50= 450/x
x^2 = 22500
x = 150
Answer:
158.4 pounds
Step-by-step explanation:
first find the volume of the tank


to convert this to m^3 we know that 1m = 100cm


the cm^3 cancel out.


by simply converting the side-lengths to meters beforehand can give you this answer directly:

it is given that 1 meter cube of water weighs about 2200 pounds.

multiply both sides with 0.072 to find our answer:


hence the weight of the water in the tank would be 158.4 pounds!
