Question

Find the value of x.

Answer 1

20

Explanation:

`V_(right\: square \: pyramid) = (1)/(3) {a}^(2) h \\ \\ \therefore \: 1500 = (1)/(3) {(15)}^(2) (x)\\ \\ \therefore \: 1500 = (1)/(\cancel 3) * \cancel {225} (x) \\ \\ \therefore \: 1500 = 75x \\ \\ \therefore \: x = (1500)/(75) \\ \\ \therefore \: x = 20`
