Answer: 100 inches

Step-by-step explanation:

From the question, we are given the information that Nia had a 20 inch by 30 inch enlargement made of a photograph and that she wanted to have it framed.

The number of inches of frame that she would use to enclose the photo will be gotten by calculating the perimeter of the shape and this will be:

= 2(length + width)

= 2(30 + 20)

= 2(50 inches)

= 100 inches

To enclose the photo, 100 inches of frame is needed.

The net of a rectangular prism is shown below. The surface area of each face is labeled. Which values represent the dimensions i
Naddika [18.5K]

Answer:

<h2>The dimensions are 3, 4 and 6 centimeters.</h2>

Step-by-step explanation:

Notice that the surface of 24 square centimeters is formed by 6 times 4, which gives 24 square centimeters.

The 12 square centimeres surface is formed by 3 times 4, which gives 12.

The 18 square centimeters surface is formed by 3 times 6, which gives 18.

Therefore, the three dimensiosn to form the prism are 3 cm x 4 cm x 6 cm.

Where 6 cm is the height, 3 cm and 4 cm are the width and length.
