Step: 1
To find the volume of the composite 3-D shape, count the number of small cubes in both A and B and add.
Step: 2
Number of small cubes filled in cuboid A is 32.
Step: 3
Volume of A is 32 × 1 cm3 = 32 cm3
Step: 4
Number of small cubes filled in cuboid B is 24.
Step: 5
Volume of B is 24 × cm3 = 24 cm3
Step: 6
Total Volume = Volume of A + Volume of B = 32 cm3 + 24 cm3 = 56 cm3
Step: 7
Volume of the composite 3-D shape is 56 cm3.
Correct Answer is : 56 cm3
