a(b + c) = a(b) + a(c)
Composite figures are made up of smaller figures (rectangles, triangles, squares, etc...). Add the area of all the smaller shapes together to get the area of the composite figure.
Surface Area is the total area of all the sides of a 3D figure. It is measured in units squared. Your units will have an exponent of 2 in your answer.
V=length x width x height
V = Base (area of the base) x height
Volume is measured in cubic units! Your units will have an exponent of 3 in your answer.
