Question

The net of a rectangular prism is shown below. What is the total surface area of the prism?

Answer 1

Answer: 40.5

Step-by-step explanation: The way you get the surface area is by multiplying the numbers given, the rectangles are given as being 1.5 x 6, and the squares at 1.5 x 1.5, so you would multiply those, and then multiply them by the number of shapes that are the same size.

The rectangles would be;

1.5 x 6 = 9

9 x 4 = 36

The squares would be;

1.5 x 1.5 = 2.25

2.25 x 2 = 4.5

Now add the final numbers together to get the final surface area;

36 + 4.5 = 40.5

I hope this helps you!
