Volume of Prisms
Volume of a 3-D figure is the number of cubic units (cubes) that are contained in its interior.
This is just like area of a 2-D figure is the number of square units contained in its interior.
Area
Volume

4. Formula

5. Volume of Prisms V = Bh Base: A = bh 15 yd = 6(8) = 48 yd²
Find the volume of each figure.
V = Bh
Ex. 1:
Base: A = bh
15 yd
= 6(8)
= 48 yd²
Volume = 48(15)
V = 720 yd³

6. 15 yd 6 yd 8 yd V = Bh Base: A = ½bh 15 yd = ½(8)(6) = 24 yd²
Ex. 2: Find the volume.
V = Bh
Base: A = ½bh
15 yd
= ½(8)(6)
15 yd
= 24 yd²
Volume = 24(15)
6 yd
8 yd
V = 360 yd³

7. Volume of Prisms 15 yd 6 yd 8 yd V = 360 yd³
Find the volume of each figure.
Ex. 1:
Ex. 2:
15 yd
6 yd
8 yd
V = 360 yd³
V = 720 yd³

8. V = Bh Base: A = ½bh 10 ft = ½(6)(4) = 12 ft² Volume = 12(10)
Ex. 3: Find the volume.
V = Bh
Base: A = ½bh
10 ft
4 ft
= ½(6)(4)
= 12 ft²
10 ft
6 ft
Volume = 12(10)
V = 120 ft³

9. V = Bh Base: A = 80 cm² 14 cm Volume = 80(14)
Ex. 4: Find the volume.
V = Bh
14 cm
Base: A = cm²
14 cm
Volume = 80(14)
Area of base (B) = 80 cm²
V = 1120 cm³
