Randy is building a cube-shaped doghouse with four faces. He is leaving one face open as a door, and one face open to the ground

astraxan [27]

Total suface area of a cube = $6 a^{2}$ , where a is the length of the cube.
Here, two faces will be left open, which reduces the formula to
total surface area = $4 a^{2}=4(4)^{2}=4\times 16=64$ square feet
