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 13 inches by width 39 inches by height 37 inches is 2515.810163 inches2.

## Surface area of a Pyramid 13 inches by 39 inches by 37 inches

Steps:

The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2} Substitute the values of the length l =13 , the width w =39 , and the height h =37 into the formula for surface area of a pyramid A=(13 \cdot39+13$$\sqrt{(\frac{39}{2})^2+(37)^2}$$+39$$\sqrt{(\frac{13}{2})^2+(37)^2}$) in

Simplify each term.

Multiply 13 in by 39 in

A = $507.0 + 13$$\sqrt{(\frac{39}{2})^2+(37)^2}$$+39$$\sqrt{(\frac{13}{2})^2+(37)^2} Square root of \sqrt{(\frac{39}{2})^2+(37)^2} is 41.8240362 Put The values in Area Formula: A= 507.0 + 13 \cdot 41.8240362 + 39$$\sqrt{(\frac{13}{2})^2 + (37)^2}$

Square Root of $\sqrt{(\frac{13}{2})^2+(37)^2}$ is 37.5666075

Put The values in Area Formula:

A= 507.0 + 13 x 41.8240362 + 39 x 37.5666075

Multiply 13 and 41.8240362

A= 507.0 + 543.71247 + 39 x 37.5666075

Multiply 39 and 37.5666075

A= 507.0 + 543.71247 + 1465.097693
