Answer:
The volume of rectangular prism is inches³
Step-by-step explanation:
Given as :
The Length of rectangular prism = L = inches
The Breadth of rectangular prism = B = inches
The Height of rectangular prism = H = inches
Let The volume of rectangular prism = V inches³
A rectangular prism is a 3-D figure with 6 faces
Now, <u>From formula of rectangular prism</u>
Volume = Length × width × height
Or, V = L × B × H
Or, V = inches ×
inches ×
inches
or, V = inches³
or, V = inches³
So, The volume of rectangular prism = V = inches³
Hence The volume of rectangular prism is inches³ Answer

By using the calculator
a = 5.875 , b = -55.25 , c = 195
So, the</span></span><span> quadratic model for the data is ⇒ y = 5.875 x²- 55.25 x + 195
============================================
