# Math Help - [SOLVED] Extra Cred Minimum Area problem (oil can)

1. ## [SOLVED] Extra Cred Minimum Area problem (oil can)

I've attached my work

An oil can is to be made in the form of a right circular cylinder to hold one quart of oil. What dimensions of the can will require the least amount of material?

i know i havent finished the problem but what i have returns an incredibly small height for the cylinder. Where have i gone wrong?

$r^3 = \frac{115.5}{4\pi}
$r \ne 11.32$
