Question

You have an aquarium in the shape of a rectangular prism. The base is 4 feet by 2 feet. The height is 3 feet. How many square feet of glass were used to build the aquarium? (The top of the aquarium is open.)

Answer 1

2(3x4+2x4) =2(12+8)= 40 square feet

4 sides, 2 are 3x4 =12 for total 24

other 2 sides are 2x4 = 8, for total 16

24 +16 = 40

that assumes an open top and no glass for the bottom, with glass on all 4 sides
