what is the height, length and width of a cereal box?
Let w = width of the front (same as back). This is also the length of one side of the top and bottom.
Let h = height of the front (same as back). This is also the length of one side of the sides.
Let d = depth of the box. [ This would the other length of the ides, top and bottom.
So, you need to find three areas, multiply each area individually by 2 and then add those together.
So Area of
front = wh. So, combined area of front and back = 2lh
Area of top = wd. So, combined area of top and bottom = 2wd
Area of side = hd. So, combined area of both sides = 2hd
Surface Area is the sum of all the areas = 2lh + 2wd + 2hd
or, SA = 2(lh + wd + hd) ]
