Answer:

The surface area of the pyramid is [tex]SA=564\ cm^{2}[/tex]

Step-by-step explanation:

we know that

The surface area of the rectangular pyramid is equal to the area of the rectangular base plus the area of its four triangular faces

so

[tex]SA=(18)(10)+2[\frac{1}{2}(18)(13)]+2[\frac{1}{2}(10)(15)]\\ \\SA=180+ 234+150\\ \\SA=564\ cm^{2}[/tex]

Answer:

564 cm^2

That's the correct answer lol
