Aright rectangular prism has base dimensions of 3 inches by 12 inches and a height of 5 inches. an oblique rectangular prism has base dimensions of 4 inches by 9 inches and a height of 5 inches. are the volumes the same?

Yes they are. Given that a volume of a rectangular prism is V=l•w•h, we can plug them into an equation and compare them. I'll call the Right rectangular prism figure R and the oblique rectangular prism O

For Figure R, We know all the basic needs to find the volume. This means we can plug it in.

V=l•w•h
V=12•3•5
Now We can solve for V
V=12•15
V=180

The volume of the right rectangular prism is 180in^3

Now, For figure O.
V=9•4•5
V=9•20
V= 180.

With this in mind, We now can say that the volumes of both the rectangular prisms are the same.

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
