When two resistance R1{R}_{1}R1​ and R2{R}_{2}R2​ connected in series and introduced into the left gap of a meter bridge and a resistance of 10Ω10\Omega10Ω is introduced into the right gap, a null point is found at 60cm60\mathrm{cm}60cm from left side. When R1{R}_{1}R1​ and R2{R}_{2}R2​ are connected in parallel and introduced into the left gap, a resistance of 3Ω3\Omega3Ω is introduced into the right-gap to get null point at 40cm40\mathrm{cm}40cm from left end. The product of R1R2{R}_{1}{R}_{2}R1​R2​ is ______ Ω2{\Omega }^{2}Ω2
