A manufacturing process creates a layered composite by stacking alternating sheets of Material A (density ρA=1.4 g/cm3\rho_A = 1.4 \text{ g/cm}^3, thickness tAt_A) and Material B (density ρB=3.2 g/cm3\rho_B = 3.2 \text{ g/cm}^3, thickness tBt_B). If the ratio tAtB=2.5\frac{t_A}{t_B} = 2.5, what is the density of the composite in the direction perpendicular to the layers?
