Find the volume of the prisms. Show work!

1. Answer =   About 1451.42 m³

First, we need to find the volume of the cube:Formula: πr²hVolume = π * 3² * 50 = 1413.72 m³Second, we need to find the volume of the cone:Formula: (πr²h)/3Volume = π * 3² * 4 = 37.69 m³Third, we need to add these two volumes to find the total volume of the figure.1413.72 m³ + 37.69 m³ = 1451.42 m³.

2. Answer = 960 m³

Formula: (1/2(b*l)) * 20First, we need to find the area of the base (1/2 * b* l).1/2 * 8 * 12 = 48.Second, we need to multiply the area of the base by the height to get the volume.B * h = 48 * 20 = 960 m³.
