Solution

## The correct option is A 6200 The length of the aquarium = l = 50 cm Width of the aquarium = b = 40 cm Height of the aquarium = h = 30 cm Area of the base = l × b = 50 × 40 = 2000 cm2 Area of the side face = b × h = 40 × 30 = 1200 cm2 Area of the back face = l × h = 50 × 30 = 1500 cm2 Required area = Area of the base + area of the back face + (2 × area of a side face) = 2000 + 1200 + (2 × 1500) = 6200 cm2 Hence the area of the coloured paper required is 6200 cm2.
