Question
Find the height $ h $ of a pyramid if side $a = 28\, \text{cm}$ and volume $V = 6533.33\, \text{cm}$.
Answer
$25\, \text{cm}^-1$
Explanation
To find height $ h $ use formula:
$$ V = \dfrac{ a ^{ 2 } \cdot h }{ 3 } $$After substituting $V = 6533.33\, \text{cm}$ and $a = 28\, \text{cm}$ we have:
$$ 6533.33\, \text{cm} = \dfrac{ 28\, \text{cm} ^{ 2 } \cdot h }{ 3 } $$$$ 6533.33\, \text{cm} \cdot 3 = 28\, \text{cm} ^{ 2 } \cdot h $$$$ 19599.99\, \text{cm} = 784\, \text{cm}^2 \cdot h $$$$ h = \dfrac{ 19599.99\, \text{cm} }{ 784\, \text{cm}^2 } $$$$ h = 25\, \text{cm}^-1 $$This page was created using
