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.
