Question

The formula $E=\sqrt{A/7}$ describes the relationship between the length of the edge E of a pyramid and the surface area A of the pyramid. How much longer is the edge of the pyramid with a surface area 3087 than the edge of one with a surface area 2023?

Answer 1

$E_1=\sqrt{\frac{3087}{7}}=21$

$E_2=\sqrt{\frac{2023}{7}}=17$

$\Rightarrow E_1-E_2=4$
