Question

find the volume of the figure.
the volume of the figure is (square) (round to the nearest whole number as needed.)

Explanation:

Step1: Identify the figure and formula

The figure is a square - based pyramid. The volume formula for a square - based pyramid is $V=\frac{1}{3}Bh$, where $B$ is the area of the base and $h$ is the height.

Step2: Calculate the area of the base

The base is a square with side length $s = 1.8$. The area of the base $B=s^{2}=1.8^{2}=3.24$.

Step3: Calculate the volume

The height $h = 2.9$. Substitute $B = 3.24$ and $h = 2.9$ into the volume formula: $V=\frac{1}{3}\times3.24\times2.9$. First, $\frac{1}{3}\times3.24 = 1.08$. Then, $1.08\times2.9=3.132$.

Step4: Round the answer

Rounding $3.132$ to the nearest whole number gives $3$.

Answer:

$3$
