1. ## base of a rectangular box is 4 inches by 2 inches. What is the height of the box...

The base of a rectangular box is 4 inches by 2 inches. What is the height of the box if the volume is 48 cubic inches?
A. 6
B. 12
C. 8
D. 24

I tried drawing a box and labeling the numbers but I do not understand what to do withe volume. Like should i do 4+4+2+2*48?

Could you please explain how to start working this problem.

***Thank you so much for taking the time to read my post and returning any advice on my problem at hand! =D

2. If the bases' dimensions are a and b, and if the height is c, the volume is:

$V = abc$

Now, we know that V = 48, and that a = 4 and b = 2, so that means:

$48 = 4(2)c$

Solve for c.

And that is the height. So the answer is a.
