For the diagonal of the floor:
20^2 + 48^2= c^2
400+2304= c^2
c=52
For the diagonal of the cube:
52^2 + 10^2 = c^2
2704+100=c^2
c=52.95
Rounded= 53
Tell me if this helps!!!

Answer:

A, the rectangular room will be in the shape of cuboid, whose dimension are

Length = 20 ft, Width=48 ft and Height = 10 ft

Length of Diagonal of floor

 [tex]=\sqrt{L^2+W^2}\\\\=\sqrt{20^2+48^2}\\\\=\sqrt{400+2304}\\\\=\sqrt {2704}\\\\=52[/tex]

Length of Diagonal of floor=52 ft

Length of diagonal of Room

[tex]=\sqrt{L^2+W^2+H^2}\\\\=\sqrt{20^2+48^2+10^2}\\\\=\sqrt{400+2304+100}\\\\=\sqrt{2804}\\\\ =52.95[/tex]

Length of diagonal of Room=52.95 ft
