A triangular prism has mass 900g, length 20cm and the triangle bases are equilateral and with side length 6cm. Find the density(g/cm^3) of the material the prism is made of.

Answer:Density is mass/volume .: mass must be identified and volume calculated.Volume of triangular prism is calculated as prism lengtharea of triangle.As triangles are equilateral and of side length 6cm area can be calculated as 15cm^2.Prism volume= triangle arealength= 15*20=300Density=mass/volume=900/300=3g/cm^3
