Question 21
In PIMSO Museum, there is a glass prism with dimensions shown in the figure. The base of the prism is a trapezium. PS = IM = 10 dm, PI = 12 dm, MS = 24 dm, and MO = 18 dm. PR is the perpendicular distance between the edges PI and MS. If the density of glass is 2500 kg/m³, determine the mass of the prism. Hint! 1 dm = 10 cm
