Question

In a right rectangular pyramid with base edges a=18 cm and b=10 cm the slant height towards a is k=13 cm while the slant height towards b is l=15 cm. Find The surface area of the pyramid

Answer 1

Answer:

The surface area of the pyramid is $SA=564\ cm^{2}$

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

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

Answer 2

Answer:

564 cm^2

That's the correct answer lol
