 $\begin{array}{r} h = & 3 \\ l = & 1.5 \\ w = & \frac{3}{4} \end{array}$

Step 1

The volume of a box is equal to the length $l$ times the width $w$ times the height $h$ .

$(l e n g t h) \cdot (w i d t h) \cdot (h e i g h t)$

Step 2

Substitute the values of the length $l = 1.5$ , the width $w = \frac{3}{4}$ , and the height $h = 3$ into the formula.

$1.5 \cdot \frac{3}{4} \cdot 3$

Step 3

Multiply $1.5 (\frac{3}{4})$ .

Step 3.1

Combine $1.5$ and $\frac{3}{4}$ .

$\frac{1.5 \cdot 3}{4} \cdot 3$

Step 3.2

Multiply $1.5$ by $3$ .

$\frac{4.5}{4} \cdot 3$

Step 4

Divide $4.5$ by $4$ .

$1.125 \cdot 3$

Step 5

Multiply $1.125$ by $3$ .

$3.375$
