The space on the faces of a cube
area (surface area)
Isis is building a birdhouse. She makes four of the faces out of rectangles with widths of 4 in. and lengths of 6 in. She makes two of the faces out of squares with sides that are 4 in. long. What is the area of all of the faces?
6X4=24 sq. in. for each rectangle face
There are four so 24 X 4 = 96 sq. in.
4X4=16 sq. in. for the area of each square face
There are two so 2 X 16 = 32 sq. in.
96+ 32 = 128 sq. in.
