Answer:
<em>780cm cubed</em>
Step-by-step explanation:
- <em>if we want to find the volume we would do length x width x height</em>
- <em>which would be 5 x 12 x 13</em>
- <em>so we would do 5 x 12 which is 60 </em>
- <em>then we would do 60 x 13 which equals 780</em>
- <em>So the answer is 780</em>
- <em>Since this is volume it would be 780cm cubed</em>
