The formula for finding the density of the wooden square pyramid is :

[tex]\text{density}=\frac{mass}{volume}[/tex]

mass given: 100,000grams (g)

The volume of the pyramid is calculated with the formula:

[tex]V=\frac{1}{3}\times base\text{ area x perpendicular height}[/tex][tex]\begin{gathered} \text{base area = l}^2 \\ l=65cm^2 \\ \text{Base area= (65)}^2 \\ \text{Base area =4225cm}^2 \end{gathered}[/tex]

Perpendicular height: 90cm

[tex]\begin{gathered} V=\frac{1}{3}\times4225\times90 \\ V=126750cm^3 \end{gathered}[/tex]

Now, we can calculate the density:
