a)\(R_1//R_2\Rightarrow R_{12}=\dfrac{R_1\cdot R_2}{R_1+R_2}=\dfrac{60\cdot40}{60+40}=24\Omega\)
\(I=\dfrac{U}{R_{tđ}}=\dfrac{12}{24}=0,5A\)
b)\(U_1=U_2=U=12V\)
\(P_1=\dfrac{U_1^2}{R_1}=\dfrac{12^2}{60}=2,4W\)
\(P_2=\dfrac{U_2^2}{R_2}=\dfrac{12^2}{40}=3,6W\)
c)CTM mới: \(R_3nt(R_1//R_2)\)
\(I'=\dfrac{I}{2}=\dfrac{0,5}{2}=0,25A\)
\(R_{tđ}=\dfrac{U}{I'}=\dfrac{12}{0,25}=48\Omega\)
\(R_3=R_{tđ}-R_{12}=48-24=24\Omega\)

Từ đề bài ta suy ra tất cả các mặt bên của hộp đều là hình thoi (được ghép từ 2 tam giác đều)
\(\Rightarrow A'D=A'B=A'A=a\Rightarrow\) hình chiếu vuông góc của A' lên (ABCD) trùng trọng tâm E của tam giác ABD
\(\widehat{DBE}=\dfrac{1}{2}.60^0=30^0\Rightarrow\widehat{CBE}=\widehat{CBD}+\widehat{DBE}=60^0+30^0=90^0\)
\(\Rightarrow BC\perp BE\)
Mà \(A'E\perp\left(ABCD\right)\Rightarrow A'E\perp BC\)
\(\Rightarrow BC\perp\left(A'BE\right)\Rightarrow BC\perp A'B\)
\(\Rightarrow B'C'\perp A'B\)
\(AE=\dfrac{2}{3}.\dfrac{a\sqrt{3}}{2}=\dfrac{a\sqrt{3}}{3}\Rightarrow A'E=\sqrt{A'A^2-AE^2}=\dfrac{a\sqrt{6}}{3}\)
Qua C' dựng đường thẳng song song A'E cắt AC tại F \(\Rightarrow C'F=A'E=\dfrac{a\sqrt{6}}{3}\)
\(CF=AE=\dfrac{a\sqrt{3}}{3}\) ; \(AC=2.\dfrac{a\sqrt{3}}{2}=a\sqrt{3}\Rightarrow AF=AC+CF=\dfrac{4a\sqrt{3}}{3}\)
\(\Rightarrow AC'=\sqrt{AF^2+C'F^2}=a\sqrt{6}\)
\(CP=\dfrac{1}{3}CC'\) ; \(CN=\dfrac{1}{3}BC\)
Nối PN kéo dài cắt BB' tại J
Talet: \(\dfrac{CP}{BJ}=\dfrac{CN}{NB}=\dfrac{1}{2}\Rightarrow BJ=2CP=\dfrac{2a}{3}\Rightarrow\dfrac{BJ}{B'J}=\dfrac{\dfrac{2a}{3}}{a+\dfrac{2a}{3}}=\dfrac{2}{5}\)
Nối JM cắt A'B' kéo dài tại K
Talet: \(\dfrac{BM}{B'K}=\dfrac{BJ}{B'J}=\dfrac{2}{5}\Rightarrow B'K=\dfrac{5BM}{2}=\dfrac{5a}{4}\)
Nối MN cắt BD tại H và cắt CD tại G
Talet: \(\dfrac{CG}{BM}=\dfrac{CN}{BN}=\dfrac{1}{2}\Rightarrow CG=\dfrac{1}{2}BM=\dfrac{a}{4}\Rightarrow DG=a+\dfrac{a}{4}=\dfrac{5a}{4}\)
Talet: \(\dfrac{BH}{DH}=\dfrac{BM}{DG}=\dfrac{a\div2}{5a\div4}=\dfrac{2}{5}\) (1)
Nối GP cắt C'D' tại Q
Talet: \(\dfrac{CG}{C'Q}=\dfrac{CP}{C'P}=\dfrac{1}{2}\Rightarrow C'Q=2CG=\dfrac{a}{2}\)
Nối QK cắt B'D' tại L
Talet: \(\dfrac{D'L}{B'L}=\dfrac{D'Q}{B'K}=\dfrac{a\div2}{5a\div4}=\dfrac{2}{5}\) (2)
(1);(2) \(\Rightarrow D'L=BH\) (do \(BD=B'D'\))
Nối HL cắt BD' tại I
Talet: \(\dfrac{D'I}{IB}=\dfrac{D'L}{BH}=1\)
Gọi F là giao điểm QK và A'D', O là giao điểm JK và A'A
Ta đồng thời suy ra luôn NPQFOM là thiết diện của (MNP) và chóp

Từ A đến C, có 4 đoạn đi lên (nằm song song nhau) và 5 đoạn đi ngang nằm song song
Ta kí hiệu đi lên là L và đi ngang là N, như vậy, số cách đi từ A đến C là số cách sắp xếp 9 kí tự bao gồm 4L và 5N
\(\Rightarrow\) Có \(\dfrac{9!}{5!.4!}\) cách
Tương tự, từ C đến B có 2L và 5N, có \(\dfrac{7!}{2!.5!}\) cách
Tổng cộng: \(\dfrac{9!}{5!.4!}.\dfrac{7!}{2!.5!}\) cách đi từ A đến B
