- Length of block = 2 inches .
- Breadth = 8 inches .
- Height = 10 inches.
- she decides to make two blocks by cutting through the block on the red line.
To Find :-
- What is the total area of the cut surfaces she still needs to paint ?

Solution :-
from image we can see that, when Janey cuts the block on the red line , she gets ,
- 2 cuboid .
now, since, whole block was painted with gold glitter , after cutting she has to paint two faces of equal area.
so,
→ Area of 1 faces that, she has to paint = Breadth of block * Height of block = Length of face * Breadth of face = 8 * 10 = 80 inches² .
then,
→ Area of 2 faces = 2 * 80 = 160 inches² (Ans.)
Hence, the total area of the cut surfaces she still needs to paint is 160 inches².
