Step-by-step explanation:
Because 12 and 11 are not the same number it could be added it it were 11^3 and 11^4. But in this case it cannot.
Answer:
DF^2=DH^2+HF^2
DF=√DH^2+HF^2
DF=√2(DH^2) {AS IT IS A CUBE THEN ALL SIDES ARE EQUAL}
DF=√2*11^2 {ALL SIDES OF A CUBE ARE EQUAL}
DF=√2*121
DF=√242
DF=15.555
THEREFORE,OPTION B..
