Question

Marcus bought a fish tank in the shape of a rectangular prism. It has a height of 2.2 feet, width of 1.8 feet, and a length of 3.3 feet. If the whole fish tank is made out of glass including the top, how much glass in square feet is used to make the fish tank?

Answer 1

34.32 sq feet

Explanation:

it is about finding the total surface area. Since it is a rectangular prism, we will have 2 identical sizes of front and back, 2 identical sizes of top and bottom, and 2 identical sizes of right and left.

therefore

front = 2.2 x 3.3 = 7.26

top = 3.3 x 1.8 = 5.94

right = 1.8 x 2.2=3.96

total SA = 2( 7.26 + 5.94 + 3.96) =34.32
