Steps:
The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2}$
Substitute the values of the length l =13 , the width w =39 , and the height h =38 into the formula for surface area of a pyramid
A=($13 \cdot39+13$$\sqrt{(\frac{39}{2})^2+(38)^2}$$+39$$\sqrt{(\frac{13}{2})^2+(38)^2}$) in
Simplify each term.
Multiply 13 in by 39 in
A = $507.0 + 13$$\sqrt{(\frac{39}{2})^2+(38)^2}$$+39$$\sqrt{(\frac{13}{2})^2+(38)^2}$
Square root of $\sqrt{(\frac{39}{2})^2+(38)^2}$ is 42.7112397
Put The values in Area Formula:
A= $507.0 + 13 \cdot 42.7112397 + 39$$\sqrt{(\frac{13}{2})^2 + (38)^2}$
Square Root of $\sqrt{(\frac{13}{2})^2+(38)^2}$ is 38.5519131
Put The values in Area Formula:
A= 507.0 + 13 x 42.7112397 + 39 x 38.5519131
Multiply 13 and 42.7112397
A= 507.0 + 555.2461166 + 39 x 38.5519131
Multiply 39 and 38.5519131
A= 507.0 + 555.2461166 + 1503.524609
Add 507.0 and 555.2461166
A=1062.2461166 + 1503.524609
A= 2565.7707256 in2
∴ The Surface Area of Pyramid length 13 in , width 39 in and height 38 in is 2565.7707256 in2
