Surface Area & Volume

Surface Area: To get the surface area of a 3D shape, like a rectangular prism, you first need to make the prism into a net. Then you find the area of the fronts,backs,sides,bottom, and the top. Then you just add them all together to get your surface area.


For volume you just use the formula "LxWxH" or length x width x height.

soo 4 x 4 x 4 = 64cm3 , this means volume = 64 cubic centimeters " 64cm3".
