What is surface area and how do you work it out?
Surface area is the area on an object. How one works it is dependent on the object.
SURFACE IS THE AREA OF ANY OBJECT. AND HOW IT WORKS IS IF YOU HAVE A SQUARE AND YOU WANT TO FIND THE PERIMITIER THEN YOU HAVE TO MAKE ALL SIDES THE SAME. SO IF YOU HAVE A SQUARE AND THE BASE IS 10FT AND THE HEIGHT IS 9 FT THEN THE OTHER BASE IS 10FT AND THE OTHER HEIGHT WOULD BE 9FT AND THEN YOU ADD BASE+HEIGHT+BASE+HEIGHT
