Solution:
Note that:
- Volume of rectangle₁ + Volume of rectangle₂ = Volume of figure
Finding the volume of rectangle₁:
- Volume of rectangle₁ = 1 x 7 x 6 = 42
Finding the volume of rectangle₂:
- Volume of rectangle₂ = 7 x 3 x 4 = 84
Finding the volume of the figure:
- 42 + 84 = Volume of figure
- => 126 cm = Volume of figure
