Answer:
A;3600 yd2
Step-by-step explanation:
The surface area is found by adding the area of the sides
The area of the bottom is
A= s^2 where s is the side length since it is a square
A = s^2 = 30^2= 900
We can find the area of one of the sides and multiply by 4 since all the sides are the same
The sides are triangles so
A = 1/2 bh where b is the base b=30 and h is the height = 45
A = 1/2 (30)* 45
A = 675
We have 4 of these triangles
4*675 =2700
Add the 4 triangles and the bottom
2700+900
3600
