There are several information's already given in the question. Based on those given information's the answer can be easily deduced.
Lateral area of the solid = 216 cm^2
Lateral edge of the solid = 9 cm
Let us assume the measure of the one side of the section = x
Then
216 = 4s * 9
216 = 36s
s = 6
From the above deduction, it can be concluded that the measure of the one side of the section is 6 cm. I hope that the answer has actually come to your help.
Answer:
The slope is 9 3/4 or 9.75

<span>4. Unit rate implies how much in one hour. If 306 miles is in 10 hours, in one hour, it will be just one-tenth of 306 miles. So divide 306 by 10. To divide by 10, just place a point before one digit from the right. So the answer will be 30.6 milers/hour.
5. Unit rate here implies how much in one month. If 33.6 gallons is in 6 months, in one month, it will be just one-sixth of 33.6 gallons. So divide 33.6 by 6. The answer will be 5.6 gallons/month.</span>
