Question

I need b, p, l, and SA of then pyramid

Answer 1

The base of the pyramid is a square, and its area is calculated as follows:

`\begin{gathered} B=side^2 \\ B=4^2 \\ B=16\text{ yd}^2 \end{gathered}`

Given that the base is a square, its perimeter is calculated as follows:

`\begin{gathered} P=4\cdot\text{side} \\ P=4\cdot4 \\ P=16\text{ yd} \end{gathered}`

The slant height, l, is shown in the diagram, its measure is l = 6 yd.

Finally, the surface area, SA, is:

`\begin{gathered} SA=B+(1)/(2)Pl \\ SA=16+(1)/(2)\cdot16\cdot6 \\ SA=16+48 \\ SA=64\text{ yd}^2 \end{gathered}`
