The standard for conversion of metric (cm) to Imperial (inches) is 1 inch = 2.54 cm. Hence 30 cm x 40 cm x 10 cm = 30/2.54 X 40 / 2.54 x 10 /2.54 = 11.811 ins. X 15.748 ins. X 3.937 ins. As an approximation 12 ins. X 16 ins. X 4 ins.
A 3-dimensional object (NOT figure) is measurement in Cubic Units). Its surface area is measuremd in Square Units. For example if we use an house brick . Its dimensions may be 9inches, x 4 inches, x 3 inches. Its volume is 9 ins X 4 ins X 3 ins. = 108 cu.ins. (Cubic Inches). Its surface are will have 6 faces. ; 2 @ (9 x 4) 2 @ ( 4 x 3 ) and 2 @ (9 x 3) So its surface area is 2(36 sq.ins) + 2(12sq. ins) + 2(27sq.ins) = 72 + 24 + 54 = 150 sq. ins. ( square inches). NB A 3-dimensional is an OBJECT A 2-dimensional us a FIGURE . A 1-dimensional is a LINE
Square root of 8900 = 89001/2 = 10 x 891/2 = 10 x 9.43398113 = 94.3398113
I'm guessing you mean: √250 - √40/2 = √(25 x 10) - √(4x10)/2 = √25 x √10 - √4 x √10/2 = 5 √10 - 2 √10/2 = 5 √10 - √10 = 4 √10
Find the largest square that is a factor. That's 100. THe answer will be 10 times the square root of 2. √200 = √2 x 100 = √2 x √100 = 10√2
Convert the feet and inches into metres and then multiply

10 is greater than square root 20 √20 = √(2 x 10) = √2 x √10 10 = √10 x √10 √10 > √2 → 10 > √20
10 × 10 × 2 = 200 square feet

(10)2 = (10 x 10) = 100
Let's x be one of the numbers, and y the other number. So, x + y = -8 xy = 6 y = -x - 8 x(-x -8) = 6 -x^2 - 8x = 6 multiply by -1 both sides x^2 + 8x = -6 solve for x by completing the square; x^2 + 8x + 16 = -6 + 16 (x + 4)^2 = 10 x + 4 = square root of 10 x = -4 + square root of 10 or x = -4 - square root of 10 if we continue to solve the system of the equations, we can find the same value for y. Thus the numbers are -4 + square root of 10 and -4 - square root of 10. Check: (-4 + square root of 10) + (-4 - square root of 10) = -4 + square root of 10 - 4 - square root of 10 = -8 (-4 + square root of 10)(-4 - square root of 10) = (-4)^2 - (square root of 10)^2 = 16 - 10 = 6
The 2' X 10' perimeter yields 20 square feet of area.
Square root of 8900 = 89001/2 = 10 x 891/2 = 10 x 9.43398113 = 94.3398113

10' x 16' is not a square but a rectangle and the diagonal is square root of (10^2 + 16^2) = square root of (100 + 256) = square root of 356 which is 18.867 feet
