What is the volume and how is it measured? 3 1/4 ft 3 ft and 3 3/4 ft.

 cubic feet

Step-by-step explanation:

If these are the width, length and height of a rectangular box (such details were not specified in the question), the volume is calculated by multiplying the three quantities because the volume of a rectangular prism is : width x height x length.

The easiest way to do it when mixed numbers are involved (specially when the denominators of the fractions are "4" like in your case), is to convert them to decimal form and then do the multiplication:

3 1/4 = 3.25

3 3/4 = 3.75

now do the product of the three quantities:

3 x 3.25 x 3.75 = 36.5625 = 36 + 0.5625

now convert 0.5625  into fraction form: 9/16 and you get the final answer (remember to include the cubic form of the units "ft" since each quantity you multiply carries a feet unit:

36  9/16  cubic feet

where r the answers

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
