A net of a triangular prism is shown below. What is the surface area, in square feet, of the triangular prism​

Answers

Answer:

[tex]Area = 152cm^2[/tex]

Step-by-step explanation:

Given

See attachment for the prism net

Required

Calculate the area

First, calculate the area of the two congruent triangle:

[tex]A_1 =2 * \frac{1}{2} * base * height[/tex]

Where

base = 6cm\ height = 4cm

So:

[tex]A_1 =2 * \frac{1}{2} * 6cm * 4cm[/tex]

[tex]A_1 =24cm^2[/tex]

Calculate the area of the middle rectangle

[tex]A_2 = Length * Width[/tex]

[tex]A_2 = 6cm * 8cm[/tex]

[tex]A_2 = 48cm^2[/tex]

Lastly, the area of the two congruent rectangles on both sides of the middle rectangle

[tex]A_3 = 2 * Length *Width[/tex]

[tex]A_3 = 2 * 8cm * 5cm[/tex]

[tex]A_3 = 80cm^2[/tex]

So, the surface area of the net is:

[tex]Area = A_1 + A_2 + A_3[/tex]

[tex]Area = 24cm^2 + 48cm^2 + 80cm^2[/tex]

[tex]Area = 152cm^2[/tex]

The PTA wants to cover the wet areas of the trail with wood chips. They find that one bag of wood chips covers a 3 1 2 -yard section of the trail. If there is a wet section of the trail that is approximately 50 1 4 yards long, how many bags of wood chips are needed to cover the wet section of the trail?

Answers

Answer: 14 5/14 bags of woods

Step-by-step explanation:

Since one bag of wood chips covers a 3 1/2 yard section of the trail and the section of the trail is 50 1/4 yards long, the number of bags of wood chips that are needed to cover the wet section of the trail will be calculated by dividing the wet section of the trail by 3 1/2. This will be:

= 50 1/4 ÷ 3 1/2

= 201/4 ÷ 7/2

= 201/4 × 2/7

= 402/28

= 201/14

= 14 5/14 bags of woods
