The value v of a square glass varies directly as the square of its length x cm. if the value of a square glass with length 3 cm is $243, find the value of a glass with length 5 cm

Given that the value V of a square glass varies directly as the square of its length X cm.

Then, the variation equation is given by



Given that value of a square glass with length 3 cm is $243, we have:



Thus, the value of a glass with length 5 cm is
