Question 323117: How would I proceed to calculate the following:
a. Cost per cubic foot = x
Calculate cost if dimensions are 30"x18"x2"

b. How does one calculate cubic root of a figure? (My calculator only has a square root button!)
Thanks in advance,

How would I proceed to calculate the following:
a. Cost per cubic foot = x
Calculate cost if dimensions are 30"x18"x2"
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%5Ey function with y = 1/3
Some have a x%5E%281%2Fy%29 too
