Question

A rectangle prism has a length of 8 feet , a width of 3 feet , and a height of 5 feet. What is the surface area of the rectangle prism?

Answer 1

Answer:

Answer is A = 158

Step-by-step explanation:

You can use the equation A = 2(wl + hl + hw)

Answer 2

Answer:

Surface area of the rectangular prism = $158\,feet^2$

Step-by-step explanation:

Surface area of a rectangular prism is:

      $=2((Length\times Width)+(Width\times Height)+(Height\times Length))$

For,

$Length=8\,feet\\\\Width=3\,feet\\\\Height=5\,feet$

Surface area of the rectangular prism for the given dimensions is :

$=2((8\times 3)+(3\times 5)+(5\times 8))\\\\=2(24+15+40)\\\\=2(79)\\\\=158\,feet^2$

Surface area of the rectangular prism = $158\,feet^2$
