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:

$V=\frac{1}{3}b\cdot h$

Then, for the pyramid in the picture we have:

$\begin{gathered} b=9\cdot9=81\text{ units}^2 \\ h=10\text{ units} \\ V=\frac{1}{3}\cdot81\cdot10=270\text{ units}^3 \end{gathered}$
