first area of the aquarium = 2(80 * 30 + 30 * 40 + 80 * 40)
=2( 2400 + 1200 + 3200)
= 13600
therefore area of paper needed = 13600 - (area of front face + area of the top)
= 13600 - ( 80 * 40 + 80 * 30 )
= 13600 - 5600
= 8000
therefore answer is 8000
=2( 2400 + 1200 + 3200)
= 13600
therefore area of paper needed = 13600 - (area of front face + area of the top)
= 13600 - ( 80 * 40 + 80 * 30 )
= 13600 - 5600
= 8000
therefore answer is 8000
