Answer:

<h2>118.13 m³</h2>

Step-by-step explanation:

Given,

Length ( l ) = 5 meters

Width ( w ) = $6 \frac{3}{4}$ meters

Height ( h ) = $3 \frac{1}{2}$ meters

Now, Let's find the volume of rectangular prism :

$volume \: = l \: \times \: w \: \times \: h$

plug the values

$= 5 \times \frac{27}{4} \times \frac{7}{2}$

Calculate the product

$= \frac{5 \times 27 \times 7}{4 \times 2}$

$= \frac{945}{8}$

$= 118.13 \: {m}^{2}$

Hope this helps..

Best regards!!
