The surface area of the prism is 144 square units

<h3>How to determine the surface area?</h3>

The attached image represents the missing figure in the question.

The image would be used to complete the steps, as follows:

Step 1: The surface area formula. Surface Area = BA + ph
Step 2: The shape of the bases are right triangles
Step 3: The area of one base; Area = 0.5 * 3 * 4 = 6
Step 4: Multiply the area in (3) by 2: BA = 2 * 6 = 12
Step 5: The perimeter of one base. p = 3 + 4 + 5 = 12
Step 6: Multiply p by h; LA = 12 * 11 = 132
Step 7: Add (4) and (6). Surface Area = 12 + 132 = 144

Hence, the surface area of the prism is 144 square units

Please help the first two answers aren’t right.

Airida [17]

It has to have an average of 10 feet per minute for 5 minutes, which means in five minutes the total of feet would have to be 50.
So you would add all these numbers up and you would get 38.
50 - 38 = 12 so the answer is 12ft
