Question

The figure below is the two-dimensional net of a rectangular prism. What is the surface area of the prism it can be folded to form.

(Please see attached picture)
8 square units
20 square units
24 square units
28 square units

Answer 1

Answer:28

Explanation:

took the test

Answer 2

For this case we must find the area of each of the rectangles that form the rectangular prism.
We have then:

Rectangle 1:

`A1 = (2) * (1) A1 = 2`

Rectangle 2:

`A2 = (2) * (4) A2 = 8`

Rectangle 3:

`A3 = (4) * (1) A3 = 4`

Then, the prism area is given by:

`A = 2A1 + 2A2 + 2A3`
Substituting values:

`A = 2 (2) + 2 (8) + 2 (4) A = 4 + 16 + 8 A = 28`

Answer:
the surface area of the prism is:
28 square units
