Question

The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only.) A triangular prism is shown with 2 right triangular sides having legs 3 and 4 and hypotenuse 5. The length of the prism is 3.5 Numerical Answers Expected! Answer for Blank 1:

Answer 1

54

Explanation:

Answer 2

54 square units

Explanation:

In order to calculate the surface area of the prism you have to calculate the area of each face of the prism, and you have to remember the different formulas to calculate the areas:

`Rectangle=Length*Width`

`Triangle=(Base*Height)/(2)`

So you just have to insert the values into the formulas:

`Rectangle1=4*3.5`

`Rectangle1=14`

`Rectangle2=5*3.5`

`Rectangle2=17.5`

`Rectangle3=3*3.5`

`Rectangle3=10.5`

`Triangle1=(4*3)/(2)`

`Triangle1=6`

`Triangle2=(4*3)/(2)`

`Triangle2=6`

If you add up all the faces, you get the surface area of the prism:

14+17.5+10.5+6+6=54
