Answer: 48yds squared
Explanation:
Hi there,
To find surface area start with multiplying the bottom side lengths to find the size of the base.
(4*4=16yds squared)
Next, find the area of one triangle on the pyramid by using the triangle area formula.
(1/2 * 4 * 4= 8yds squared)
We know that pyramids are made out of four triangles, so multiply the surface area of one triangle by 4.
(8 * 4 = 32 yds squared)
Now, add the base area to the area of the triangles to find total surface area.
(32+16= 48 yds squared)
Hope this helps.
