If the rent for a safe deposit box for a volume of 1 cu in is 50 dollars per year, what would be the rent for the given safe deposit box?
Length of the box = 30 in
Width of the box = 16 in
Height of the box = 20 in
Volume = length×width×height
= 30×16× 20 = 9600 cu in
Cost of rent per cu in = 50 dollars.
For 9600 cu in, cost = 9600 × 50 = 480,000 dollars
