In general when you think of a cube you think volume. Which would be 12 * 7 * 5 or 420 cubic feet.
However, if you mean the area of the outer rectangles, then you need to think about each of the 6 sides. To figure out the area of each side you take the length times the width.
There are 2 sides that are 12ft x 7ft - area of 74 ft each, or 148 for both
There are 2 sides that are 12ft x 5ft - area of 60 ft each, or 120 for both
and there are 2 that are 7ft x 5ft - area of 35 ft each, or 70 for both
So the total area would be 338 square feet

How many inches is 5' 7?
To convert 5 feet 7 inches to inches, first convert the feet to inches by multiplying by 12. There are 5 feet, which is 5 x 12 = 60 inches. Then, add the additional 7 inches: 60 + 7 = 67 inches. Therefore, 5 feet 7 inches is equal to 67 inches.
How many square feet are in a room that measures 12x7?
Assuming the room measures 12 feet by 7 feet - and there is absolutely no reason to make that assumption as against 12 cubits x 7 cubits - the area is 12*7 = 84 square feet.
Ruth has 12 feet of ribbon.She uses 7 feet of it for a craft project and gives 28 inches of it to her sister.How many inches of ribbon does she have left?
She started with 12, so after giving 7 feet for her craft project she has 12-7=5 feet left. There's 12 inches in a foot, so 5 feet is 5*12 = 60 inches. She gave 28 inches to her sister, so 60-28 = 32 inches remaining.
