An aquarium is in the form of a cuboid whose external measures are cm*cm*cm.The base, side faces are to be covered with a coloured paper. Find the area of the paper needed?

$\huge\bf{\red{\underline\green{Answer:-}}}$

Area of paper required = area of base + 2 area of side + area of back

=>(80×30)+2(30×40)+(80×40)

=>2400+2400+3200

=>8000^2cm
