Question

Simpson has a rectangular fish aquarium that measures 31 inches long, 13 inches wide, and is 28 inches deep. If Simpson wanted to put a protective covering on the four glass walls of the aquarium, how much covering does he need?

Answer 1

Area of the four walls = 2(Length x height) + 2(Width x height)

Area of the four walls = 2(21 x 28) + 2(13 x 28)

Area of the four walls = 1176 + 728

Area of the four walls = 1904 in²

Answer: Total area of the 4 walls = 1904 in²
