Explanation:
The step by step calculations is as shown in the attached file.
Answer:

Answer:
volume of a rectangular prism = 77.616
Given:
length = 5.6 cm
width = 2.1 cm
height =6.6 cm
To find:
volume of a rectangular prism = ?
Formula:
volume of a rectangular prism = length × width × height
Solution:
volume of a rectangular prism = length × width × height
volume of a rectangular prism = 5.6 × 2.1 ×6.6
volume of a rectangular prism = 77.616
