Answer:
<em>1620in³</em>
Step-by-step explanation:
Volume of a rectangular prism = BH
B is the Base area
H is the height of the prism.
Given
B = 180in²
H = 9in
get the volume of the prism
Volume of the prism = 180 * 9
Volume of the prism = 1620in³
<em>Hence the volume of the rectangular prism is 1620in³</em>
