Assuming no loss in the cutting, how would I would cut 3 strips of 32 cm long, each subdivided into 8 pieces of 15 cm wide. This will take care of 24 pupils.
For the remaining 4 students, we cut in the direction, giving an extra length of 30 cm. with some waste.
The total length is therefore
3*32+2*15=116 cm
If we had cut in the same direction for everyone, there will be more waste, with a total length of 4*32=128 cm.
