51 inches wide x 30 inches long = 10.625 square feet.
15 square feet.
3 x 30 = 90 square feet. 1 square foot = 144 square inches (12 x 12) So 90 square feet = 12,960 square inches
7.5 square feet.
8.33 square feet.
There are 2.5 feet in 30 inches. 30 inches x 1 foot/12 inches = 2.5 feet 1 foot = 12 inches
12 inches = 1 foot therefore 30 inches = 2 feet 6 inches.
62" x 30" x 30" = 32.292 cubic feet. (rounded)
Feet x 12 = inches. Therefore 2.5 feet = 2.5 x 12 = 30 inches.
51 inches wide x 30 inches long = 10.625 square feet.
36 inches X 360 inches X 4 inches = 30 cubic feet.
1 feet = 12 inches 12 inches =1 foot 1 inch=1/12 30 inches=1/12 x 30 30 inches=5/2 30 inches=2.5 feet
There are 12 inches in one foot. There are 3 feet in one yard. Therefore, 30 yards 2 feet is equal to (30 x 3 x 12) + (2 x 12) = 1104 inches.
Area calculation: 30 inches by 30 inches = (30 x 30) square inches =900 square inches or, if you want square feet instead: 12 inches x 12 inches (1 square foot) = 144 square inches Take your 900 square inches and divide by 144 to get square feet. 900 / 144 = 6.25 square feet
There are 12 inches in 1 foot so there are 12 x 30 inches, which is 360 inches, in 30 feet.
5 square feet
Hint:12 inches = 1 foot. Over to you... 30 feet = 30 x 12 inches = 360 inches
