Surface area of a Pyramid 71 inches by 96 inches by 35 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 71 inches by width 96 inches by height 35 inches is 15819.6015264 inches².

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 =96 , and the height h =35 into the formula for surface area of a pyramid

A=($71 \cdot96+71$$\sqrt{(\frac{96}{2})^2+(35)^2}$$+96$$\sqrt{(\frac{71}{2})^2+(35)^2}$) in

Simplify each term.

Multiply 71 in by 96 in

A = $6816.0 + 71$$\sqrt{(\frac{96}{2})^2+(35)^2}$$+96$$\sqrt{(\frac{71}{2})^2+(35)^2}$

Square root of $\sqrt{(\frac{96}{2})^2+(35)^2}$ is 59.405387

Put The values in Area Formula:

A= $6816.0 + 71 \cdot 59.405387 + 96$$\sqrt{(\frac{71}{2})^2 + (35)^2}$

Square Root of $\sqrt{(\frac{71}{2})^2+(35)^2}$ is 49.8522818

Put The values in Area Formula:

A= 6816.0 + 71 x 59.405387 + 96 x 49.8522818

Multiply 71 and 59.405387

A= 6816.0 + 4217.7824742 + 96 x 49.8522818

Multiply 96 and 49.8522818

A= 6816.0 + 4217.7824742 + 4785.8190522

Add 6816.0 and 4217.7824742

A=11033.7824742 + 4785.8190522

A= 15819.6015264 in²

∴ The Surface Area of Pyramid length 71 in , width 96 in and height 35 in is 15819.6015264 in²
