First, split the figure into 2. Now you have a triangular prism and a rectangular prism.
1.6m-1.2m=0.4m ( height of triangular prism)
Area of triangular prism= height x breadth x length = 0.4m x 3m x 5m =6m2
Area of rectanglular prism = 1.2m x 3m x 5m
= 18m2
Total volume = 6m2 +18m2 = 24m2
1.6m-1.2m=0.4m ( height of triangular prism)
Area of triangular prism= height x breadth x length = 0.4m x 3m x 5m =6m2
Area of rectanglular prism = 1.2m x 3m x 5m
= 18m2
Total volume = 6m2 +18m2 = 24m2
