A tent in the shape of a triangular prism is made using the following piece of fabric find the surface area of the fabric explain your reasoning

The answer to your question is 204 cm²

Step-by-step explanation:

Process

1.- Calculate the area of the first rectangle from up.

Area = base x width

        = 10 x 5

        = 50 cm²

2.- Calculate the area of the middle rectangle

Area = 10 x 8

        = 80 cm²

3.- Calculate the area of the lowest rectangle

Area = 10 x 5

        = 50 cm²

4.- Area of the rectangular faces

Area = 50 + 80 + 50

        = 180 cm²

5.- Calculate the area of the triangles

Area = base x height / 2

        = 8 x 3 /2

        = 24/2

        12 cm²

6.- Area of the triangles

Area = 12 + 12

        = 24 cm²

8.- Total area

Total area = 180 + 24

                 = 204 cm²

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

The total nom of  code that can be used is equal to 5+3 = 8

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg
