Answer:
V = 240 
Step-by-step explanation:
To find the volume of a rectangular prism use this equation: 
V = l*w*h
l = length (20 cm) 
w = width (4 cm) 
h = height (3 cm) 
Plug all these values into the equation and solve: 
V = (20 cm)(4 cm)(3 cm) 
V = (80  )(3 cm)
)(3 cm) 
V = 240 
Therefore, the volume of the rectangular prism is 240  .
