Question

Annika needs to find the volume of this square pyramid. What answer should she get?

Answer 1

The volume of a pyramid with base b and height h is given by:

`V=(1)/(3)b\cdot h`

Then, for the pyramid in the picture we have:

`\begin{gathered} b=9\cdot9=81\text{ units}^2 \\ h=10\text{ units} \\ V=(1)/(3)\cdot81\cdot10=270\text{ units}^3 \end{gathered}`
