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 71 centimeters by width 37 centimeters by height 87 centimeters is 12418.7810463 centimeters2.

## Surface area of a Pyramid 71 centimeters by 37 centimeters by 87 centimeters

Steps:

The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2} Substitute the values of the length l =71 , the width w =37 , and the height h =87 into the formula for surface area of a pyramid A=(71 \cdot37+71$$\sqrt{(\frac{37}{2})^2+(87)^2}$$+37$$\sqrt{(\frac{71}{2})^2+(87)^2}$) cm

Simplify each term.

Multiply 71 cm by 37 cm

A = $2627.0 + 71$$\sqrt{(\frac{37}{2})^2+(87)^2}$$+37$$\sqrt{(\frac{71}{2})^2+(87)^2} Square root of \sqrt{(\frac{37}{2})^2+(87)^2} is 88.9452079 Put The values in Area Formula: A= 2627.0 + 71 \cdot 88.9452079 + 37$$\sqrt{(\frac{71}{2})^2 + (87)^2}$

Square Root of $\sqrt{(\frac{71}{2})^2+(87)^2}$ is 93.9640889

Put The values in Area Formula:

A= 2627.0 + 71 x 88.9452079 + 37 x 93.9640889

Multiply 71 and 88.9452079

A= 2627.0 + 6315.1097576 + 37 x 93.9640889

Multiply 37 and 93.9640889

A= 2627.0 + 6315.1097576 + 3476.6712887

Add 2627.0 and 6315.1097576

A=8942.1097576 + 3476.6712887

A= 12418.7810463 cm2

∴ The Surface Area of Pyramid length 71 cm , width 37 cm and height 87 cm is 12418.7810463 cm2
