Question

Find the surface area of the solid below. Round to the nearest tenth if needed.

Answer 1

1350

Explanation:

Answer 2

2400 ft²

Explanation:

Base = 30x30=900

Next, we have to find the height of the triangles.

15²+20²=c²

225+400=c²

625=c²

c=√625

c=25

Now we can find the surface area of all 4 triangles.

4(1/2)(30)(25)=1500

900+1500= 2400 ft²
