Question

Some of the dimensions of a square pyramid are shown in the diagram. The height of the square pyramid is 7.5 meters. What is the volume of the square pyramid in cubic meters? A. 202.5 m B. 303.75 m C 270 m D 243 m

Answer 1

We are to find the volume of the square pyramid

`\begin{gathered} \text{The }volumeofthesquarepyramid\text{ =}(1)/(3)a^2h \\ \text{Where a is the area of the base} \\ \text{where h is the height} \\ \text{Given } \\ h\text{ =7.5m L=9} \\ a^2=l^2 \\ a^2=81 \\ \text{The }volumeofthesquarepyramid=(1)/(3)*81*7.5 \\ \\ \text{The }volumeofthesquarepyramid=202.5\text{ cubic meters} \end{gathered}`
