Question

Find the volume of a pyramid with a square base, where the area of the base is 6.8m^2
and the height of the pyramid is 8.6. Round your answer to the nearest tenth of a cubic meter.

Answer 1

Answer:

$19.5\:\mathrm{m^3}$

Step-by-step explanation:

The volume of a square pyramid is given by $V=\frac{1}{3}\cdot s^2\cdot h$, where $s$ is the base edge and $h$ is the height. Since the base area ($s^2$) is already given to us, we can substitute directly in to our equation.

Solving for $V$:

$V=\frac{1}{3}\cdot 6.8\cdot 8.6\approx \boxed{19.5\:\mathrm{m^3}}$
