The length breadth and height of a cuboidal box is 2 meters 10cm, 1m and 80cm. Find the area of the canvas.

Given,


length (l) = 210 cm


breadth (b) = 100 cm


height (h) = 80 cm


Area of canvas = Total surface area of cube = 2(lb +bh + hl)


= 2[(210)(100) + (100)(80) + (80)(210)]


= 2[21000 + 8000 + 16800]


= 2 × 45800


= 91600cm2


So, Area of canvas is 916 m2
