The square root of 900 is ±30 because 30 * 30 = 900 and -30 x -30 = 900
30 square inches converts to about 193.55 square centimeters.
30" x 30" = 900 square inches.
It is: 24 times 30 = 720 square inches
900 square inches in total.
30 in × 42 in = 1260 sq in
30 inches by 10 feet = 25 square feet.
2.5 Square feet is 30" x 30" or 360 Square Inches
30 inches by 5 feet = 12.5 square feet.
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
5 square feet
30 x 18 = 540 square inches. 540 square inches converts to 3.75 square feet.
30 * 36 = 1080 square inches = 1080/144 = 7.5 sq. feet.
