Use the formula v= lwh to find the volume of a Rectangular prism with the following dimensions :

L= 7in
W= 4in
H= 3in

To find the volume of the rectangular prism, you need to multiply the length, width, and height together:

V = lwh
V = (7in)(4in)(3in)
V = 28in² * 3in
V = 84in³

So, the volume of the rectangular prism is 84 cubic inches.
