Desperately need help finding the Volume of an Oatmeal Box

[fredncharlotte]

I am having troubles finding the answer to the following problem:

Find the voume of an oatmeal box that is 12 inches high and has a diameter of 5 inches. Use 3.14 for pi.

I know that the volume of a rectangle is: V=LWH, but there is nothing in the problem about the length and width.

Thanks in advance for any help that you can give me!

Hello, Fred!

Find the voume of an oatmeal box that is 12 inches high and has a diameter of 5 inches. Use 3.14 for pi.

You're expected to know the formula for the volume of a cylinder: . V . = . π·r²·h

You are given: . π = 3.14, .r = 2.5, .h = 12

. . . Go for it!

Thanks! I was thinking of a rectangle because it stated that it was a box. Now I know to use the following equation:
V=height x pi x r squared.
