212 in.2
is 212 in.2 the right answer ?
Apologies for the error in my previous response. Let's review the options together based on the net of the rectangular prism:
Looking at the net of the rectangular prism, we can identify the following dimensions for each rectangle:
- The front and back faces: 3 units x 5 units = 15 units² each
- The top and bottom faces: 3 units x 4 units = 12 units² each
- The two side faces: 5 units x 4 units = 20 units² each
To find the total surface area, we add the areas of all these faces together:
Front + Back + Top + Bottom + 2(Side1 + Side2)
= 15 + 15 + 12 + 12 + (20 + 20)
= 30 + 24 + 40
= 94 units²
Therefore, the surface area of the rectangular prism is 94 units². Since this number was not among the original multiple-choice options, it seems there may have been some confusion in the provided answers.
