Answer:
84cm^2
Step-by-step explanation:
The pyramid's SA is the square at the bottom plus the triangles on the side.
The square is 6x6=36.
Per triangle, it's BxH/2. B=6. H=4. Therefore, per triangle has a SA of 12 cm^2.
There are 4 triangles. 48 cm^2 in total for the triangles
36cm^2+48cm^2=84cm^2
The blank is 25.
Tip: There is already 25, so there is only 50. But they want half so, half of 50 is 25.
I hope you understand.
