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?
1 answer:
Answer:
34.32 sq feet
Step-by-step 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
