How do you find volume and surface area?

The volume for a rectangular pyramid is (LWH)/3, meaning to multiply the length by the width by the height and then divide the product by 3.
Since I've explained how to solve this, let's start solving!
Our length and width are 2, and our height is 3.
Multiply our length by our width by our height.
3 x 2 x 2 = 6 x 2 = 12.
Remember when finding volume, we're dealing with a 3rd dimension, so our unit of measure is ^3.
Your volume is 12in^3.
The surface area for a rectangular pyramid is 16.65 in^2. I hope this helps!
