The document provides examples of calculating the total volume of combination 3D shapes by finding the individual volumes of each component shape and adding them together. In each example, the dimensions of the cubes and cuboids that make up the combination shape are given, and their individual volumes are calculated as length x width x height and summed to find the total volume.

1. Find the volume of a combination 3D shape. 3 cm 4 cm 2 cm 6 cm Volume A ( cube ) 3 cm X 3 cm X 3 cm = 27 cm 3 Volume B ( cuboid ) 6 cm X 4 cm X 2 cm = 48 cm 3 Volume A + Volume B = 27 cm 3 + 48 cm 3 = 75 cm 3 A B answer : 75 cm 3 Example
2. 1.) Find the volume of a combination 3D shape. 4 cm 9 cm 2 cm 4 cm 4 cm Volume A ( cube ) 4cm X 4cm X 4cm = 64 cm 3 Volume B ( cuboid ) 9cm X 4cm X 2cm = 72 cm 3 Volume A + Volume B = 64 cm 3 + 72 cm 3 = 136 cm 3 A B answer : 136 cm 3
3. 2.) Find the volume of a combination 3D shape. 2m 3m 2m 5m 2m Volume A ( cuboid ) 5m X 2m X cm = 30 m 3 Volume B ( cuboid ) 2m X 2m X 8m = 32 m 3 Volume A + Volume B = 30 m 3 + 32 m 3 = 62 m 3 A B 8m answer : 62 m 3
4. 3.) Find the volume of a combination 3D shape. 2cm Volume A ( cuboid ) 5cm X 2cm X 2cm = 20 m 3 Volume B ( cuboid ) 7cm X 2cm X 2cm = 28 cm 3 Volume C ( cube ) 2cm X 2cm X 2cm = 8 cm 3 Volume A + Volume B + Volume C = 20 cm 3 + 28 cm 3 + 8 cm 3 = 56 m 3 answer : 56 cm 3 2cm 2cm 2cm 2cm 5cm 7cm A B C
