21 ft.
20ft x 10ft x 7ft = 1400 cubic feet 1 yard of dirt = 27 cubic feet Hence yards required = 1400/27 = 51.85
It is: 7 times 3 = 21 square feet
multiply them all toether!
In yards, the room is 3 yards by 7/3 yards. By multiplying those numbers together, you see that the area is 7 square yards.
21 ft.
It is: 10*7*3 = 210 cubic feet
20ft x 10ft x 7ft = 1400 cubic feet 1 yard of dirt = 27 cubic feet Hence yards required = 1400/27 = 51.85
Area = 7ft*7ft = 49 ft2
The area is the product of (Length) times (Width)6ft by 10ft = (6 x 10) = 60 square feet.
7ft by 7ft
The area of a circle if the diameter was s 7ft is 38.48ft
7ft x 7ft = 63ft squared
The surface area of a cylinder with a radius of 6ft and a height of 7ft is 490.09ft2
It is: 7 times 3 = 21 square feet
multiply them all toether!
10ft X 10ft = 100sq ft /9 = 11.11 sq yds
