Chapter 11 project: Salsa Jar that has a volume of 81 units. **All Volumes are unit cubed** ﻿**;** **All Surface Ares are unit cubed** 4/12 3*3*9 and Surface Area= 126 units cubed Rectangular Prism 9*9*2 and Surface Area= Triangular Prism Rectangular Prism Formula: l*w*h = Volume Triangular Prism: .5*l*w*h = Volume SA= 187.2 we unfolded the 3-D shape and found the area of each 2-D shape. Then add all areas together. Cylinder (Circular Prism)Formula: (pi)r squared*h = Volume SA= 106 Break the 3-D shape into a 2-D drawing and add all the areas together. To find the Volume of any Prism find the area of the base shape and multiply times the height of the prism. Rectangular Prism V= l*w*h Rectangular Pyramid V= 1/3(l*w*h) Volume of a Cylinder (Circular Prism) Today Sam worked on the smart notebook and I did the triangular Prism.
