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

A=2(l+w)h+l×w
A=2(4+2)×3+4×2
A=36+8
A=44 square feet, so there are 44 square feet of glasses were used to build aquarium. Hope it help!
