Answer :
Answer:
40 ft^2
Step-by-step explanation:
lateral surface area -Slat = 24 ft^2
top surface area-Stop = 8 ft^2
bottom surface area-Sbot = ft m^2
24+8+8= 40
total surface area-Stot = 40 ft^2
The surface area of a rectangular prism or cedar chest of 2 feet tall, 4 feet wide, and 2 feet deep is 40ft sq.
The length of a rectangular prism is 2 feet.
The width of a rectangular prism is 4 feet.
The height of a rectangular prism is 2 feet.
we need to find the surface area of a rectangular prism.
What is a rectangular prism?
A rectangular prism is a 3-dimensional representation, that has six rectangular faces two at the top and bottom and four are lateral faces. A rectangular prism is also known as a cuboid.
The surface area of a rectangular prism = 2(lb + bh + lh)
So, the surface area of a rectangular prism = 2(lb + bh + lh)
[tex]=2(2\times4+4\times2+2\times2)\\=2(8+8+4)\\=40[/tex]
Hence, the surface area of a rectangular prism or cedar chest is 40ft sq.
