<PRE><B>Question 323117</B>
How would I proceed to calculate the following: 
a. Cost per cubic foot = x
Calculate cost if dimensions are 30&quot;x18&quot;x2&quot;
Find the volume in cubic inches = 30*18*2 = 1080 cubic inches
1 foot = 12 inches
1 cubic foot = 12*12*12 cubic inches = 1728
Vol = 1080/1728 cu ft
= 0.625 cubic feet
----------------------
b. How does one calculate cubic root of a figure? (My calculator only has a square root button!) 
Use the {{{x^y}}} function with y = 1/3
Some have a {{{x^(1/y)}}} too
