 $\begin{array}{r} h = & 2 \\ l = & 7 \\ w = & 3 \end{array}$

Step 1

The volume of a pyramid is equal to $\frac{1}{3} \cdot (l e n g t h) \cdot (w i d t h) \cdot (h e i g h t)$ .

$\frac{1}{3} \cdot (l e n g t h) \cdot (w i d t h) \cdot (h e i g h t)$

Step 2

Substitute the values of the length $l = 7$ , the width $w = 3$ , and the height $h = 2$ into the formula to find the volume of the pyramid.

$\frac{1}{3} \cdot 7 \cdot 3 \cdot 2$

Step 3

Combine $\frac{1}{3}$ and $7$ .

$\frac{7}{3} \cdot 3 \cdot 2$

Step 4

Cancel the common factor of $3$ .
