exis [7]

Answer:

25.38

Step-by-step explanation:

Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.

20^2+12^2=c^2

400+144=544=c^2

c=\sqrt{544}

then find corner of floor to opposite roof corner.

100+544=644=c^2

c=\sqrt{644}

so its about 25.38 feet
