### Volume of Prisms

1. 1. Volume of Rectangular & Triangular PrismsSTAAR Chart Formula V = Bh* *where B equals the area of the baseSince the base shape of a rectangular prismis a rectangle, we replace B with the formulafor the area of rectangle which = bh.Giving us … V = (bh)h
2. 2. Height of V = Bh1. Figure name Shape of figure______________ Rectangular prism base? V = (bh)h 10 in 4in 3in rectangle V = (4·3)(10) 10 in V = 12·10 = 120 in³
3. 3. 1. Figure name Height of V = Bh______________ Shape of cube figure base? V = (bh)(h) 3 in3in 3in square V = (3·3)(3) V = 27 in³ 3 in
4. 4. Volume of Triangular PrismsSTAAR Chart Formula V = Bh**where B equals the area of the base and hequals the distance between the basesSince the base shape of a triangular prism 1 is a triangle, we replace B with bh . 2 1Specific formula: V bh h 2
5. 5. Height of1. Figure name Shape of the figure V = Bh______________ triangular prism base? 10 cm V = (½bh)(h) triangle V = (½ ·3·4)(10) V = 6·10 = 60 cm³4cm 10 cm 3 cm
6. 6. 1. Figure name Height of V = Bh______________ Shape of triangular prism figure base? V = (½ bh)(h) 4m 10 m triangle V = (½ · 6 · 4)(10) V = 12 · 10 = 120 m³ 10 m 6m
