 $\begin{array}{r} h = & b \\ l = & 11 \\ w = & 9 \end{array}$

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 $l = 11$ , the width $w = 9$ , and the height $h = b$ into the formula to find the volume of the pyramid.

$\frac{1}{3} \cdot 11 \cdot 9 \cdot b$

Step 3

Combine $\frac{1}{3}$ and $11$ .

$\frac{11}{3} \cdot 9 \cdot b$

Step 4

Cancel the common factor of $3$ .

Step 4.1

Factor $3$ out of $9$ .

$\frac{11}{3} \cdot (3 (3)) \cdot b$

Step 4.2

Cancel the common factor.

$\frac{11}{3} \cdot (3 \cdot 3) \cdot b$

Step 4.3

Rewrite the expression.

$11 \cdot 3 \cdot b$

Step 5

Multiply $11$ by $3$ .

$33 b$
