Label the 3 distinct sides of the box. I arbitrarily chose the letters a, b and c.
Use the info about areas as follows:
ab=54 in^2
ac=90 in^2
bc=60 in^2
Here you have 3 equations in 3 unknowns (a, b and c), which is enough info to use to determine a, b and c. Then the volume of the box is a*b*c.
Example: bc = 90, but c = 60/b. You could subst. 60/b for c in the 2nd and 3rd equation, which will eliminate c completely and leave you with 2 equations in 2 unknowns.
Continuing this procedure, I determined that a=9, b=6 and c=10. Thus, the volume of the box is V = 9*6*10 = 540 cubic inches (answer)
Jeff has -15$ his gf faith gives him 7.
Use the formula above to find the surface area of a cylinder.
For the given cylinder the given data is the height (6mi) and diameter (16mi), use the diameter to find the radius:
Surface area:
Then, the surface area of the given cylinder is: 224π square miles
A) The situation represents an arithmetic sequence because the successive y-values have a common difference of 210.
F(1) = 240 +210
F(2) = 240 +2(210)
F(3) = 240+3(210)

Answer:
6.4 inches
Step-by-step explanation:
We are going to have to use ratio's here. We know that 1 inch = 2.5 feet and we know that Terrance is making a scale model of a car that is 16 feet long. We need to work out the length of the car in inches so,
1 inches = 2.5 feet
? inches = 16 feet
→ We are going to divide 16 by 2.5 and then multiply that answer by 1 to get our result so
16 ÷ 2.5 = 6.4
6.4 × 1 = 6.4
The final answer is 6.4 inches
