# Surface area of a Pyramid 57 yards by 69 foot by 70 inches Calculator

The surface area of a pyramid is equal to the sum of the areas of each side of the pyramid. The base of the pyramid has area l x w , and sl and sw represent the slant height on the length and slant height on the width. If the Pyramid has a length 57 yards by width 69 foot by height 70 inches is 2073.4682982 yards^{2} or 3412144.8028608 inches^{2} or 23695.4500188 foot^{2}

## Surface area of a Pyramid 57 yards by 69 foot by 70 inches

**Steps:**

**The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2}$**

Substitute the values of the length l = 57 yd, the width w = 69 ft and the height h = 70 in into the formula for surface area of a pyramid

## Unit Conversion of 70 in = 1.9444444 yd

To convert Inche to Yards

we know that, **1 Inche = 0.02778 Yards or 1 Inche = 1/36 Yards**

To convert Inche to Yards, divide the inche value by 36

Result in Foot: 70 × in/12 × yd/in

Cancel The Comman factor of in

Result in Foot: 70/36

Divide the 70 by 36

Result in Yards: 1.9444444 yards

** ∴ 70 Inche = 1.9444444 yards **

## Unit Conversion of 69 ft = 23.0 yd

To convert Feet to Yards

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

Result in Yards: 69 × ft/yd × ft/yd

Cancel The Comman factor of ft

Result in Yards: 69/3 yd

Divide the 69 by 3

Result in Yards: 23.0 yards

** ∴ 69 Feet = 23.0 yards **

A=($57 \cdot23.0+57$$\sqrt{(\frac{23.0}{2})^2+(1.9444444)^2}$$+23.0$$\sqrt{(\frac{57}{2})^2+(1.9444444)^2}$) yd

Simplify each term.

Multiply 57 yd by 23.0 yd

A = $1311.0+57$$\sqrt{(\frac{23.0}{2})^2+(1.9444444)^2}$$+23.0$$\sqrt{(\frac{57}{2})^2+(1.9444444)^2}$

Square root of $\sqrt{(\frac{23.0}{2})^2+(1.9444444)^2}$ is 11.663227

Put The values in Area Formula:

A= $1311.0+ 57 \cdot 11.663227+23.0$$\sqrt{(\frac{57}{2})^2+(1.9444444)^2}$

Put The values in Area Formula:

A= 1311.0 + (57 x 11.663227) + (23.0 x 4.2462765)

Multiply 57 and 11.663227

A= 1311.0 + 664.8039389 + (23.0 x 4.2462765)

Multiply 23.0 and 4.2462765

A= 1311.0 + 664.8039389 + 97.6643593

Add 1311.0 and 664.8039389

A= 1975.8039389 + 97.6643593

A= 2073.4682982 yd^{2}

∴ The Surface Area of Pyramid length 57 yd , width 69 ft and height 70 in is 2073.4682982 yd^{2}
