Surface area of a Pyramid 86 meters by 78 meters by 70 meters Calculator
The Surface Area of Pyramid 86 meters by width 78 meters by height 70 meters is 20007.1574682 meters2.
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 86 meters by width 78 meters by height 70 meters is 20007.1574682 meters2.

Steps:
The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2}$
Substitute the values of the length l =86 , the width w =78 , and the height h =70 into the formula for surface area of a pyramid
A=($86 \cdot78+86$$\sqrt{(\frac{78}{2})^2+(70)^2}$$+78$$\sqrt{(\frac{86}{2})^2+(70)^2}$) m
Simplify each term.
Multiply 86 m by 78 m
A = $6708.0 + 86$$\sqrt{(\frac{78}{2})^2+(70)^2}$$+78$$\sqrt{(\frac{86}{2})^2+(70)^2}$
Square root of $\sqrt{(\frac{78}{2})^2+(70)^2}$ is 80.1311425
Put The values in Area Formula:
A= $6708.0 + 86 \cdot 80.1311425 + 78$$\sqrt{(\frac{86}{2})^2 + (70)^2}$
Square Root of $\sqrt{(\frac{86}{2})^2+(70)^2}$ is 82.1522976
Put The values in Area Formula:
A= 6708.0 + 86 x 80.1311425 + 78 x 82.1522976
Multiply 86 and 80.1311425
A= 6708.0 + 6891.2782559 + 78 x 82.1522976
Multiply 78 and 82.1522976
A= 6708.0 + 6891.2782559 + 6407.8792123
Add 6708.0 and 6891.2782559
A=13599.2782559 + 6407.8792123
A= 20007.1574682 m2
∴ The Surface Area of Pyramid length 86 m , width 78 m and height 70 m is 20007.1574682 m2
