Question

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?

• A. 2,90,000 dollars
• B. 4,80,000 dollars
• C. 2,38,000 dollars
• D. 1,29,000 dollars

Answer 1

The correct option is B 4,80,000 dollars

The given box is in the shape of a cuboid.

Length of the box = 30 in

Width of the box = 16 in

Height of the box = 20 in

Volume = length$\times$width$\times$height

= 30$\times$16$\times$ 20 = 9600 cu in

Cost of rent per cu in = 50 dollars.

For 9600 cu in, cost = 9600 $\times$ 50 = 4,80,000 dollars
