Surface area of a Box length 21 yards by width 18 centimeters by height 29 foot is 418.0734926 yards2 or 3762.6614208 foot2 or 3495626.8416 centimeters2

The Surface Area of a Box is equal to the sum of the areas of each side of the box. If the box has a length 21 yards by width 18 centimeters by height 29 foot is 418.0734926 yards2 or 3762.6614208 foot2 or 3495626.8416 centimeters2

Steps:

The Surface Area of a Box 2 * (length * width) + 2 * (length * height) + 2 * (width * height)

Substitute the values of the length l = 21 yd , the width w = 18 cm , and the height h = 29 ft into the formula

      Unit Conversion of 29 ft = 9.6666667 yd

29 Feet is 9.6666667 yards

To convert Feet to Yards

we know that, 1 Foot = 0.333333 or
                        1 Foot = 1/3 Yards

To convert Feet to Yards, divide the feet value by 3

Result in Yards: 29 × ft/yd × ft/yd

Cancel The Comman factor of ft

Result in Yards: 29/3 yd

Divide the 29 by 3

Result in Yards: 9.6666667 yards

∴ 29 Feet = 9.6666667 yards

      Unit Conversion of 18 cm = 0.1968504 yd

18 Centimeter is 0.1968504 yards

To convert Centimeter to Yards

we know that, 1 Centimeter = 0.0109361 Yards or
                         1 Centimeter = 1/91.44 Yard

To convert Centimeter to Yards, divide the yards value by 91.44

Result in Yards: 18 × cm/91.44 × yd/cm

Cancel The Comman factor of cm

Result in Yards: 18/91.44 yd

Divide 18 by 91.44

Result in Yards: 0.1968504 yards

∴ 18 Centimeter = 0.1968504 yards


2 * (21 yd * 0.1968504 yd) + 2 * (21 yd* 9.6666667 yd) + 2 * (0.1968504 yd* 0.1968504 yd)

Simplify each term

2 * 203.0000007 yd2 + 2 * 4.1338584 yd2 + 2 * 1.9028872 yd2

Multiply each term with 2

406.0000014 yd2 + 8.2677168 cm2 + 3.8057744 yd2

Simplify by adding three(3) term or numbers

Surface area = 418.0734926 yd2

∴ Surface area of a Box length 21 yd , width 18 cm and height 29 ft is 418.0734926 yd2

or

      Unit Conversion of 18 cm = 0.5905512 ft

18 Centimeters is 0.5905512 foot

To convert Centimeters to Feet

we know that, 1 Centimeter = 0.032809 Feet or
                         1 Centimeter = 1/30.48 Feet

To convert Centimeters to Foot, multiply the centimeter value by 30.84.

Result in Foot: 18 × cm/30.84 × ft/cm

Cancel The Comman factor of cm

Result in Foot: 18/30.84 ft

DIvide the 18 by 30.84

Result in Feet: 0.5905512 feet

∴ 18 Centimeters = 0.5905512 foot

      Unit Conversion of 21 yd = 63.0 ft

21 Yards is 63.0 foots

To convert Yards to Foot

we know that, 1 Yards = 3 Feet

To convert Yards to Foot, multiply the yard value by 3.

Result in Feet: 21 yd x 3 × ft/yd

Cancel The Comman factor of yd

Result in Feet: (21 x 3 ft)

Multiply 21 into 3

Result in Feet: 63.0 feets

∴ 21 Yards = 63.0 foots


2 * (63.0 ft * 0.5905512 ft) + 2 * (63.0 ft* 29 ft) + 2 * (0.5905512 ft* 29 ft)

Simplify each term

2 * 37.2047256 ft2 + 2 * 1827.0 ft2 + 2 * 17.1259848 ft2

Multiply each term with 2

74.4094512 ft2 + 3654.0 ft2 + 34.2519696 ft2

Simplify by adding three(3) term or numbers

Surface area = 3762.6614208 ft2

∴ Surface area of a Box length 21 yd , width 18 cm and height 29 ft is 3762.6614208 ft2

or

      Unit Conversion of 21 yd = 1920.24 cm

21 Yards is 1920.24 Centimeters

To convert Yard to Centimeters

we know that, 1 Yard = 91.44 Centimeters

To convert Yards to Centimeters, multiply the yard value by 91.44

Result in Centimeters: 21 yd x 91.44 × cm/yd

Cancel The Comman factor of yd

Result in Centimeters: (21 x 91.44 cm)

Multiply 21 into 91.44

Result in Centimeters: 1920.24 Centimeters

∴ 21 Yards = 1920.24 Centimeters

      Unit Conversion of 29 ft = 883.92 cm

29 Foot is 883.92 Centimeters

To convert Foot to Centimeters

we know that, 1 Foot = 30.480 Centimeters

To convert Foot to Centimeters, multiply the foot value by 30.480

Result in Centimeters: 29 ft × 30.480 × cm/ft

Cancel The Comman factor of ft

Result in Centimeters: (29 x 30.480 cm)

Multiply 29 into 30.480

Result in Centimeters: 883.92 Centimeters

∴ 29 Foot = 883.92 Centimeters


2 * (1920.24 cm * 18 cm) + 2 * (1920.24 cm* 883.92 cm) + 2 * (18 cm* 883.92 cm)
