Answer:
Step-by-step explanation:
The volume is [tex]\frac{1}{3} BAh\\[/tex]
where BA is the base area of the pyramid and h the slant height
BA for square pyramid = 5*9 = 45
Volume = [tex]\frac{1}{3} * 45 * 6 = 90[/tex]
[tex]\ SA = BA + 2 *\frac{1}{2} * 5*6 + 2 *\frac{1}{2} * 9 * 6[/tex]
SA = 45 + 30 + 54 = 124
