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 is A = 158

Explanation:

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

Answer 2

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

Explanation:

Surface area of a rectangular prism is:

`=2((Length* Width)+(Width* Height)+(Height* Length))`

For,

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

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

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

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