Just remember folks...the flu (influenza) is an upper respiratory infection...nausea and vomiting are not symptoms of the flu . ...So many times people say they have the flu but it really is not..
Length x width x height equals volume. * * * * *. But only if the object in question is a cuboid (rectangular prism). Length*Width*Height for a sphere, for example, does not equal its volume.
0 0. Since the statement, the length is twice its width  puts one dimension in terms of the other it's easiest to use w as the variable. So, w = width. 2w = length. The perimeter is the sum off all the sides of the rectangle. P = w + w + l + l = 2w + 2l. Using our terms and the value of 60, substitute them into the equation.
