Question

Given that the surface area of a rectangular prism is given by the formula SA = 2lw + 2lh + 2wh, what is the value of SA if h =

1
2
cm, l = 8 cm, and w = 6 cm?

Answer 1

110

Explanation:

I took the test :)

Answer 2

The surface area of the rectangular prism is given by:

`SA = 2lw + 2lh + 2wh`

Where,

l: length

w: width

h: height

Therefore, substituting values we have:

`SA = 2 (8) (6) + 2 (8) ((1)/(2)) + 2 (6) ((1)/(2))`

Rewriting we have:

`SA = 96 + 8 + 6`

`SA = 110`

Answer:

The value of the supercifial area is given by:

`SA = 110`
