The square pyramid has a volume of 441 cubic inches. what is the value of x? 1/7x is the height x is the base
Answers: 2
![\dfrac{1}{3}x^2\left(\dfrac{1}{7}x\right)=441\\\\\dfrac{1}{21}x^3=441\qquad\text{multiply both sides by 21}\\\\x^3=9,261\to x=\sqrt[3]{9,261}](/tpl/images/0001/1967/19840.png)
![\sqrt[3]{9,261}=21](/tpl/images/0001/1967/ec980.png)
![\begin{array}{c|c}9,261&3\\3,087&3\\1,029&3\\343&7\\49&7\\7&7\\1\end{array}\\\\9,261=3^3\cdot7^3\\\\\sqrt[3]{9,261}=\sqrt[3]{3^3\cdot7^3}=\sqrt[3]{3^3}\cdot\sqrt[3]{7^3}=3\cdot7=21](/tpl/images/0001/1967/978ae.png)
