If the volume of the pyramid is 81 in cubed, and l equals w equals 3 h, what is the length of the base of the pyramid in inches?
Answers: 1
![81 = \frac{3h \times 3h \times h}{3}\\\\81 = 3h^3\\\\h^3 = 27\\\\\text{Take cube root on both sides }\\\\h = \sqrt[3]{27} \\\\h = \sqrt[3]{3 \times 3 \times 3} = \sqrt[3]{3^3} \\\\h = 3](/tpl/images/0458/9491/52fda.png)
