Find the area in square inches and divide by 144. (1 ft2 = 144 in2) Or, convert each side to feet by dividing by 12 (1 ft = 12 in) and then find the area which will be in square feet.
Those are units of area.
It is 42 inches.
11,664 in2

Every face of a cube is a square so 25 in2
Area = 144 sq inches => Length of side, L = 12 inches => Perimeter = 4*L = 48 inches.
Incorrect units in the question.A volume is a cubic measurement (in3 [cubic inches]) if anything not in2 [square inches]If the volume were 8000 in3 the length of a side would be the third root of 8000 or exactly 20 in
Area=Length*Width A=14 Inches*2 Inches A= 28 square inches or 28 in2
A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.
11 x 8 = 88 square inches (88 in2)
A circle with circumference 30 in has area = 302 ÷ (4π) ≈ 71.6 in2 < 100 in2 so a square of area 100 in2 cannot fit inside it.
36 in2
Each face of the cube has 1/6 of the area = 78/6 = 13 in2 .Each side of the face = square root of the area = sqrt(13) inches .The volume of the cube is (side length)3 = [ sqrt(13) ]3 = 46.872 in3 (rounded)
A square with an area of 400 square units has a perimeter of 80 units.
