Which physical quantity has the dimension M2L-2T-2   ie., (Mass)2X(length)-2X(time)-2 ?.

Given the dimensional formula: [M2L-2T-2]
The quantity with such a dimensional formula can be obtained by mutiplying force with density
Dimensional formula of Force =mass× acceleration = M×LT-2  = [MLT-2]
Dimensional formula of Density = mass / volume = M / L3 =     [ML-3T0]
On multiplying force and density we get the dimensional formula - [M2L-2T-2]
i.e. [MLT-2]×[ML-3T0] =[M2L-2T-2]
The quantity with dimensional formula [M2L-2T-2] is Force times density
