We are not given a specific group that was surveyed, so all we would do is add all the students.
32 + 23 + 31 + 12 + 8 + 30 + 11 = 154
We end up with 154 students that were surveyed.

Answer:
Step-by-step explanation:
The surface area of each face of a sugar cube is 1*1 = 1 units²
The rectangular box has 6 faces in contact with sugar cubes.
The area of each of two faces is 18*6 = 108 units²
Therefore these two faces touch 2*108 = 216 cubes
There are two other faces each of area 18*8 = 144 units²
Therefore these two faces touch 288 cubes.
There are another two faces, each of area 6*8 = 48 units².
Therefore these faces touch 96 cubes.
The total number of cubes touching the faces of the box are
216 + 288 + 96 = 600
Answer: 600 cubes
