AREA V.S. VOLUME
A) B)
First side) 4 x 3=12 12 x 2= 24 First side ) 2 x 1=2 2 x 2=4
Second side) 2 x 3=6 6 x 2=12 Second side) 2 x 1=2 2 x 2=4
Third side) 2 x 4= 8 8 x 2=16 Third side) 2 x 4= 8 8 x 2= 16
Area of the cubed rectangle: 24+12+16=52 Fourth side) 1 x 4= 4 4 x 4= 16
Area of the cubed Lego shaped bleacher: 4+4+16+16 = 40

We’ve revisited the age of lego and constructed structures of shapes and forms. We’ve used these mini-bricks/lego to represent volume and area.
So the difference?
1. We’ve reviewed today that an Area is based off the “face” of the shape/form and that “face” only, that’s why an Area is 2D and squared whereas volume is 3D and cubed. Volume can also tell us the spacing in the shape/form of the 3D object.
2. Area and Volume also differs in its formula, for ex. the fomula for Area of a rectangle would be L x W . Volume, instead would be L x W x H
3. Areas can also be solved on 3D objects like cubes and such but Volumes cannot be solved for 2D.
