Question

How do you find the volume and surface area?

Answer 1

The find the volume and you will have to know the formula for it.
Formula for Volume: L x W x H

How to find surface area: Find the area for all of the faces the shape has then add them all up to find the surface area.

In this case of the volume :19x10x12=2,280
Surface area:(19x12)+(19x12)+(10x19)+(10x19)+(12x10)+(12x10)=956

Answer 2

To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.
