Q19- dimensions of the cuboid are 80×30×40
Therefore , total surface are of the cuboid =2 (80×30+30×40+80×30)=13600cm²
Area not covered =area of the upper face +area of the front face=80×30+80×40=5600
Now , area of the face covered =total surface area -area not covered =13600-5600= 8000cm²
Hence the area of the paper needed is 8000cm²
(Present it as it is)
